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...
