Chapter 1 - Solutions

The Lewis structures are given below. Note that in counting sigma and pi bonds, all single bonds are sigma bonds. For double bonds there is one sigma bond and one pi bond, and for triple bonds there is one sigma bond and two pi bonds. So a 4 sigma bonds and 0 pi bonds. b 5 sigma bonds and 1 pi bond. c 7 sigma bonds and 3 pi bonds ................
