Question
Explain why the energy of activation for products 1 and 2 to revert back to allylic carbocation A is much less than the Eact for 2-bromobutane to revert to the sec-butyl carbocation (the Markovnikov addition product from reaction of HBr with 1-butene). Hint: How do the carbocations formed in each case compare in stability?)Explanation / Answer
order of stability of carbocations are benzylic = allylic > tertiary > secondary > primary as we see , allylic carbocation is more stable due to resonance compared to secondary carbocation. Hence activation energy is less in case of allylic carbocation case compared to other one.
