Passage 11 (Questions 1-9) Dienes, a special group of alkenes, can be classified as conjugated or isolated. Conjugated dienes are alkenes with alternating double and single bonds. Isolated dienes have double bonds separated by more than one single bond. One explanation for this observation is the hybridization theory. According to the hybridization theory, the stability of conjugated dienes comes from the hybridization of the orbitals forming the carbon-carbon single bonds. For example, in 1,4-pentadiene, the C-C single bonds result from...

A. Double bonds that are connected by a single bond are said to be conjugated. For each molecule below, indicate how many conjugated double bonds are present in each molecule. HO OH bro HO B. One feature that distinguishes conjugated dienes from isolated dienes is that the C-C bond joining the two double bonds is unusually short. For each of the molecules in Part A, indicate which C-C single bond(s) might be shorter than expected. C. Some reactions of conjugated...
