CHEMISTRY 3221: Fundamentals of Organic Chemistry Lab I, Spring 2021***Disclaimer: Your instructor has the authority to modify the terms and conditions of this syllabus at any time.*** Due to the corona virus pandemic, major adjustments have been made to this laboratory course. These adjustments are necessary and unavoidable. Results, especially in organic synthesis, are related to the skill and?technique?of the chemist performing the reaction. ?Skill cannot be developed and honed by watching a video.Lab Coordinator: Dr. Mary Bean, mbean3@uh.edu, If your TA cannot satisfactorily resolve an issue, contact the Lab Coordinator as soon as possible. The end of the semester after grades are in is not the time to report problems. (Example: If the TA is not returning the graded lab reports in a timely manner, let the Lab Coordinator know asap.) Since there are 33-35 sections of organic lab every semester, include the course number (3221 or 3222), the 5 digit class number, and your TA’s name in any email to the lab coordinator. Please do not just say, “I’m in organic lab.” Your TA’s name:_______________________ Office hours:_________________ Email address: ________________________Summary of the online lab (Important details throughout the syllabus – Don’t just read the summary.):Lab Check-in: On the day and at the time for your lab in the first week of class, join the Microsoft Team for your lab section. The CHEM 3221 Team for your lab section is available by clicking the Teams icon in AccessUH which requires your CougarNet login information. The TA will call roll and give an introductory lecture. Your TA will also send an email with important information to your @uh.edu email account (not your @cougarnet.uh.edu email account). If you miss the Team meeting roll call, you MUST reply to the TA’s email by 11:59 PM of that day to verify that you intend to continue in the lab. In the email, include your full name and student ID number. If you do not either attend roll call or reply to the email, you may be dropped to add students who are waiting to enroll.Lab Videos: Pre-Lab Lecture: A video of each pre-lab lecture will be available all semester. This lecture covers theory and how to safely perform each experiment or reaction. It is available at this link: Video: Each week a video of a TA performing the experiment will be posted at the following link: will only be available on the dates indicated in “Experiment Schedule and Information” that may be found in this syllabus. It will be removed at 11:59 PM on the last day of the indicated time period. Even though this is a synchronous class, you may watch the video at any time while the video is available. Due date of report: Listed with each experiment in “Experiment Schedule and Information”. Instructions for submission of the lab report:A laboratory notebook (described below) will be used to prepare reports. Pdf’s from scans or .jpg (.jpeg) or .png files from good quality photos of the report will be submitted to Blackboard. It must be posted by 11:59 PM on the due date or it will be counted late. ALWAYS check your email for confirmation that your report was successfully uploaded. In the event that you have trouble with submission to Blackboard, you may email the pdf to your TA. It must arrive in your TA’s inbox by 11:59 PM on the due date. Quizzes: There will be four quizzes scheduled by the TA during the lab period throughout the semester. The TA will send you the schedule in an introductory email on the first day of lab. A make-up quiz will be given in the last week of lab to replace any quiz missed with a reasonable excuse. This quiz may not be used to replace a quiz with a lower grade. For the laboratory you will need the following items:The textbook: “UH Organic Chemistry Laboratory: CHEM 3221/3222, Second Edition”. This is a custom manual published by Cengage Learning. Do not remove any pages or write in the manual, and the Bookstore MAY buy it back.A laboratory notebook that is permanently bound, has serially numbered pages, and allows you to make a removable carbon copy that can be scanned for grading. The following PPE would be required if you were actually in the lab and was required for the TA’s who made the videos:A laboratory coat that is long-sleeved and knee lengthSturdy, closed-toed shoes that cover the entire foot. Sandals or shoes that leave a large area of the foot exposed are NOT allowed!Safety goggles (NOT SAFETY GLASSES). The laboratory coat and goggles must be worn in the laboratory at all times anyone in the laboratory is doing experimental work.Long pants or other garment that completely covers the legs. Shorts or short skirts are NOT allowed in the lab.Nitrile or latex gloves (provided by the chemistry department) Grading Policies:Lab Reports: 75% of the grade (A copy of the report format is included in the syllabus.) Any experiments performed on the same day constitute one lab report, so there are eleven lab reports for the semester. There are no make-up labs. See Make-Up policy below.In a normal semester, 50% of the lab report grade would be based on factors such as yield and purity determined by melting point and TLC of a product (results) and 50% would be based on the thoroughness and quality of the write-up (effort). Of course, you can’t be held accountable for the results, good or bad, of the TA performing the experiment.The report grades will be based on answers to questions, astute observations of experimental details, techniques, and data, calculations, and the quality of your write-up. Quizzes: 25% of gradeLetter grade definitions:A = superior performanceB = very good performanceC = average performanceD = poor performanceF = failingPlease notice that the grade definitions are couched in terms of performance achieved not effort expended. The letter grades are determined by the lab coordinator and are determined by comparing the average in a given section to the overall average of all of the sections. If a TA’s stricter than average grading results in a lower class average, that section may receive a curve upward to compensate for the difference. If a TA’s more lenient than average grading results in a much higher class average, that section may receive a curve downward to compensate for the difference.The +/- letter grade system is used.Academic Honesty Policy:The organic chemistry laboratory is a class just like any other class. As a result, you are expected to do your own work. There are no lab partners in the organic chemistry laboratory, and all work is to be done individually. This includes, but is not limited to, writing up of your lab reports and taking quizzes. You are not allowed to work with or consult others on your lab reports or quizzes. Reminder: Plagiarism is CHEATING. Copying directly from any source (the lab manual, a website, Chegg, another student, a lab report from another semester) is plagiarism.Special Note for Quizzes: The quizzes are essentially open-book quizzes. You are allowed to consult the lab manual, the Wade textbook, and your lab reports. However, you are expected to follow these rules of academic honesty: no help from other students or persons, no help from any online information or website. Make-Up Policy:Missed Labs: If a lab is missed due to a reason listed in the official UH Excused Absence Policy, it will be excused. The missed lab report grade will be replaced with the average of your lab reports. To receive an excused absence, the absence and excuse must be immediately reported by email to the lab coordinator (Dr. Bean). You may copy the TA. In the email request, include the course number (3221 or 3222), the 5 digit class number, and your TA’s name.According to the UH Excused Absence Policy, the limit for excused absences is 15% of the work, i.e., two lab reports. If absences extend beyond 15 % of the work, this is considered an extended absence. Please refer to the UH Excused Absence Policy for possible resolution in the event absences exceed the limit.The UH Excused Absence Policy may be found here: Lab Report Policy: The penalty for a late lab report is 10 points per day. Under extreme, verifiable circumstances, the lab coordinator, not the TA, may adjust this penalty. UH CAPS Statement:Counseling and Psychological Services (CAPS) can help students who are having difficulties managing stress, adjusting to college, or feeling sad and hopeless. You can reach CAPS (uh.edu/caps) by calling 713-743-5454 during and after business hours for routine appointments or if you or someone you know is in crisis. No appointment is necessary for the “Let's Talk” program, a drop-in consultation service at convenient locations and hours around campus. Care of Equipment and Reagents: (This section has been left in the syllabus, because it will be important to properly handle equipment and reagents in future labs.)Much of the equipment used in scientific laboratories is surprisingly expensive. Over the last few years more than two hundred thousand dollars has been invested in upgrading the equipment and laboratory facilities in the organic laboratories alone. It is obvious that the equipment recently added must be maintained in good condition for many years, since it cannot be replaced very often. If it is to have a satisfactory lifetime, you must cooperate by using it correctly.Most importantly, the balances must not be abused by having chemicals spilled on them. To avoid doing so place on the balance pan only a container which is clean and dry on the outside, and NEVER ADD CHEMICALS TO THE CONTAINER WHILE IT IS ON THE BALANCE PAN. First remove the container to the desk top nearby, add the chemicals, then return the container to the balance for reweighing. If you are observed violating this rule, you may be publicly reprimanded and/or expelled from the laboratory with a failing grade in the course. No kidding.Place no liquid waste in the sinks except those approved for disposal down the drain. All others must be placed in the properly labeled waste bottles provided for them.Place no solid wastes of any kind in the sinks or drain troughs. Boiling chips are particularly hard on drains. Keep them out of the sinks.Reagent bottles must be capped at all times they are not actually being used. You must replace the cap on each bottle as soon as you have finished using it. Never uncap more than one bottle at a time. Never transfer solid material from the bottle to the inverted bottle cap. Use a weighing boat for that purpose. Never leave unlabeled materials in weighing boats, etc., on the benchtop. If proper techniques are used, there is little occasion for chemicals to be spilled on the benchtops near the balances, or on the hood surfaces. Any chemicals spilled should be cleaned off immediately by the person spilling them using a method appropriate to the substance spilled. The Laboratory Notebook:The laboratory notebook is intended to be the primary, contemporaneously kept record of what you do and observe in the laboratory. Although it should be kept as legibly as possible, accuracy and completeness are its major goals, rather than neatness. All experimental observations should be made directly in the laboratory notebook with ink. It should be carried to the balance, and the weight measured recorded there. It should accompany you to the melting point apparatus, and so forth.Corrections of the record must be made in such a way that the original observation remains legible. Simply draw one line through the item to be deleted, and write in the corrected entry. Never erase, white out, or otherwise attempt to alter the original or the carbon copy. The carbon copy is handed in. The original remains in the notebook. When writing, be sure to press hard enough that the carbon copy is legible. If a page in the notebook is skipped within a report, draw an “X” across the page and hand it in with the report. The Laboratory Report Format:The information written in your laboratory notebook will constitute your Laboratory reports. Be sure to include your name, your TA’s name and the 5 digit class # at the top of the first page of each report. The format for the report is as follows:I. Title and DateThis section simply gives the title of the experiment and the date it was (will be) performed.II. Answers to the Pre-Laboratory Exercises.This section includes the answers to the assigned pre-laboratory questions.III. Introductiona. Purpose: This section includes a brief explanation of why you are doing the experiment.b. Background: This section includes a discussion of the theory behind the experiment and the importance or applications of the technique or process. If the experiment involves a chemical reaction, provide the mechanism. Please do not exceed 3 paragraphs.IV. ReactionsIf the lab involves carrying out a chemical reaction, you must write the chemical equation by drawing the structures of the reactants and products. Omit this section, if no reactions are involved.V. Table of Physical ConstantsThis section is a table that lists all of the chemicals that will be used in the experiment, including any products formed, as well as physical data for each compound: molecular weight (g/mol), melting point (°C), boiling point (°C), density (g/ml), and hazards. This information can be obtained from handbooks such as the “CRC Handbook of Chemistry and Physics” (library) or at various websites such as , , or . Click on the MSDS for each compound to find the physical data.VI. Experimental Procedure/Observations/DataThis section includes a detailed description of what the TA did while in the laboratory and a diagram or sketch of any apparatus used for the experiment or reaction. Be particular about reporting the actual amounts of materials used (not the amount given in the lab manual) and any modifications to the original procedure. Avoid simply copying the original procedure. Include any important observations made during each step such as color changes, precipitation, dissolving of solids, gas evolution, etc. At the end of this section, record any data collected such as melting points, weights, etc. This section is to be written as you view the video. Pause the video if necessary. VII. CalculationsThis section includes calculations such as Rf values, theoretical yields, percent yields and percent recoveries. Any time a reaction is carried out, it will be necessary to calculate a theoretical and percent yield. If no calculations are needed for the experiment, this section is omitted.VIII. Results and DiscussionThis section includes the results of the experiment as well as the interpretation of any observations made during the experiment. This is where the yield and melting point or boiling point should be discussed. Additionally, include whether the results of the experiment were as expected. If they were different from the expected results, give a reasonable explanation as to why.IX. ConclusionThis section includes an overall evaluation of the results. It should be one to two paragraphs in length and include statements indicating what was learned in the experiment. Additionally, include any modifications to the TA’s procedure or technique that might improve the outcome of the experiment. Mention any safety issues or improper techniques observed during the video. X. Answers to Post-Laboratory QuestionsThis section includes the answers to the assigned post-laboratory questions.Sections I-V should be completed (in your notebook) before viewing the video. Section VI is to be written as you view the video. Pause the video when needed. This is how the experimental procedure would be written if you were performing the experiment. It is not a procedure that is written down before you begin and then followed.Sections VII-X may be written after viewing the video.Experiment Schedule and Information:NOTE: Few lab manuals are perfect. Sometimes adjustments in procedure need to be made for the best results. The syllabus describes most of these changes, but additional changes may sometimes be necessary. It is the responsibility of the student to make note of any such change when given by the TA.SPECIAL NOTE: Before you watch each experiment video, be sure to watch the corresponding pre-lab lecture video. This video will explain the experiment. Again, the pre-lab video link is: experiment video link is: SPECIAL NOTE: Many TA’s worked hard to prepare the videos that we use in the online 3221 and 3222 labs. They received no compensation (other than my gratitude!) for this extra work that was above and beyond their responsibilities.None of these graduate students are trained videographers, but many produced nearly perfect videos! Some videos may be a little less perfect. As you watch the videos, you may notice a few, usually minor mistakes. Be sure to make note of these in your lab report if you spot any. A few possibilities are listed below. (You wouldn’t want to make these mistakes when/if you take 3222.)A common “mistake”, which was usually not the fault of the TA, was having the hood sash (the glass panel) at the proper working height. At the proper height, the hood sash provides protection and helps regulate airflow. This height is marked on the side of the hood. However, when in the correct position, it limited camera angles and produced a glare in the video. Incorrect use or lack of clamps and incorrect thermometer bulb positions may be observed. Always check the diagram of the apparatus in the lab manual. Finally, perhaps we should change the term to “ice water bath”. A proper ice bath is a slurry of ice and water, not just ice.Lab Schedule: Jan. 19-25Lab Check-in: See details on first page about Teams meeting and email. Watch video on Lab Safety. Read the Safety Guidelines on page 1 of the lab manual. Jan. 26-Feb. 1Prelaboratory preparation: Read Measuring Melting Points of Compounds and Mixtures, pp. 27-35. You may disregard the procedure described in Part 2. Answer in you laboratory notebook Prelaboratory questions 1, 2, 4, 5, pp. 39-40.Read Purifying Acetanilide by Recrystallization, pp 41-49. Answer in your laboratory notebook Prelaboratory questions 1-4, pp. 53-54.EXPERIMENTS: Melting pointsPart 1: The TA will use benzoic acid only. Part 2: Omit procedure, but you must know the definitions of eutectic point and eutectic composition. Part 3: Perform as written. The possible unknown compounds may be found in Table 1 on p. 35.Recrystallization: Perform as written. The starting amount of acetanilide may be changed.Additional notes:In an experimental procedure, the specification of a quantity as, for example, “60 mg of benzoic acid” does not mean precisely 60 mg, but rather about 60 mg weighed to the precision of the balance. Always record the actual mass weighed for use (example 59.51 mg), not the mass specified in the procedure (60 mg). To insure reproducibility in weighing, always use the same balance when you tare the container and later when you weigh the container plus the recrystallized material.Postlab questions: 4-6, p. 37 and 1- 3, p. 51. (Special note for #2, p. 51: Include answers in the Results and Discussion section of the report. Remember to use the correct starting amount of acetanilide.)Reports due: Wednesday, Feb. 3Feb. 2-8Prelaboratory preparation: Read pages 1 – 12 of the lab text.

Use the simple distillation apparatus pictured in Fig. 3 on p.6. Instead of a graduated cylinder, use a round bottom flask as the receiver. Use a heating mantel for the heat source.Simple distill the mixture until about 1 mL is left in the pot. Transfer the distillate to a centrifuge tube. Allow the layers to separate and remove the water layer with a pipet. Add approximately 1 gram of sodium sulfate instead of calcium chloride to the tube, cap, shake, and allow to stand for 10 minutes. Using a clean, dry pipet, transfer the dried product to a pre-weighed sample vial. Boiling point is not determined. Weigh the product and determine the % yield of the isomer mixture.Part C: Gas Chromatography: Dissolve 2-3 drops of product in 1 mL of pentane. Download and print the chromatograms. Compare your chromatogram to the standards posted. Identify the product peaks and estimate the ratio of products produced. Part D: Perform as written with product and blank only. Postlab questions: 3,4, p. 165.Reports due: Wednesday, April 7Apr. 6-12Read Grignard Synthesis of Triphenylmethanol and Benzoic Acid, pp. 167-171, and 178-181. Prelab questions: 1 on p. 182 Note: The key to success in this reaction is a dry environment! Carefully dry all glassware as described by the TA. Immediately replace the caps on all reagents used, especially the ether. Experiments: Triphenylmethanol will be synthesized in parts 4, 5, and 7 on pp. 178-181 with the following changes.Overall changes: The reaction will be performed at half the scale indicated in the procedure. In other words, all quantities will be cut in half. The solvent for the reaction will be THF (tetrahydrofuran) rather than diethyl ether. The solvent for extraction will be TBME (t-butyl methyl ether). Both of these ethers are safer than diethyl ether.Part 4: Use the apparatus pictured on the last page of the syllabus. Dry the apparatus using a heat gun (fancy hair dryer) rather than a bunsen burner. Without the drying tubes in place, dry the apparatus from bottom to top. Once vapor may no longer be seen condensing inside the apparatus, add the drying tubes. Also dry and then cap with aluminum foil a 10 mL graduated cylinder and 50 mL graduated cylinder.While the apparatus cools, obtain the Mg. Crush a few pieces to expose fresh surface and then add to the apparatus, opening and closing it as quickly as possible. Add approximately 35 mL of THF to the 50 mL graduated cylinder and cap tightly with the foil. Add the bromobenzene and about 25 mL of the THF to the addition funnel. Be sure to tightly cover the remaining THF in the graduated cylinder for later use. Run just enough of the solution into to the reaction flask to cover the magnesium.When reaction begins, one or more of the following may be observed. The surface of the metal becomes discolored, the solution becomes cloudy, bubbling is evident (bubbling alone is not an indicator). If the reaction has not begun in about 5 minutes, gently warm with a hot water bath. It the reaction does not begin, ask the TA to add catalyst.After the reaction begins, add the remaining THF/bromobenzene solution at a rate of about 1-2 drops/sec. Follow remaining procedure as written except as the reaction rate slows, warm with a beaker filled with hot water from the tap. Do not use a heating mantel or hot plate. Part 5: Lift the drying tube and add the methyl benzoate and THF to the addition funnel. Replace drying tube. Follow remaining procedure as written.Part 7: Follow the procedure as written through drying the ether layer (combination of THF and TBME) over calcium chloride except extract the aqueous layer twice with TBME and combine the extracts before drying. Filter the ether into a round bottom flask and evaporate the ether using the rotary evaporator. Save a small sample of the crude product for TLC analysis.Triturate (mix and stir) the crude product (residue in the round bottom) with cold petroleum ether to remove the side product biphenyl. The biphenyl dissolves in the petroleum ether. The triphenylmethanol does not dissolve. Remove the petroleum ether by decanting or suction filtration. Save a sample of the petroleum ether for TLC analysis.Recrystallize the crude product from isopropyl alcohol. Record the mass and melting point of the pure triphenylmethanol. Analyze the crude product, the petroleum ether extract, and the recrystallized product by TLC using petroleum ether as the eluent.

The UH administration has required that I add the following to this syllabus:University of Houston Syllabus LanguageSpring 2021Required Language Face Covering Policy (required for courses with a face-to-face component)To reduce the spread of COVID-19, the University requires face coverings on campus including classrooms for both faculty and students. Face coverings must cover your mouth and nose and be worn throughout the class session. A mask with a valve is not considered an adequate face covering and should not be used, as it can expel exhaled air, increasing the risk to others. Eating or drinking during class is discouraged and is not an excuse for removing the face covering for any extended length of time. For additional information on the use of face coverings, please see Face Covering FAQs. Failure to comply with the requirement to wear a face covering in class will result in your being asked to leave the classroom immediately and a disciplinary referral through the Dean of Students Office. Requests for accommodations relating to the face covering policy may be directed to the Center for Students with DisABILITIES (CSD).Required Daily Health Self-Assessment (required for courses with a face-to-face component)Your presence in class each session means that you have completed a daily self-assessment of your health/exposure and you: Are NOT exhibiting any?Coronavirus SymptomsHave NOT tested positive for COVID-19Have NOT knowingly been exposed to someone with COVID-19 or suspected/presumed COVID-19If you are experiencing any COVID-19 symptoms that are not clearly related to a pre-existing medical condition, do not come to class. Please see?COVID-19 Diagnosis/Symptoms Protocols?for what to do if you experience symptoms and?Potential Exposure to Coronavirus?for what to do if you have potentially been exposed to COVID-19. Consult the (select: Undergraduate Excused Absence Policy or Graduate Excused Absence Policy) for information regarding excused absences due to medical reasons. Excused Absence Policy (required for all courses)Regular class attendance, participation, and engagement in coursework are important contributors to student success.
