Question

Acid catalysed dehydration of tertiary butyl alcohol occurs faster than n butyl alcohol why

Answer 1

dehydration of alcohols undergoes through the formation of carbocation intermediate. t-butyl alcohol forms t-butyl cation which is a stable carbocation..so it undergoes dehydration at higher rate.

In case n-butanol it forms less stable carbocation n-butyl cation..which farther undergoes hydride shift to from stable carbocation..but the after accepting protone it forms n-butyl cation and which generate in a slower rate as the intermediate carbocation is not stable..

Thats the reason t-butyl alcohol under goes dehydration at faster rate
