    Why is acid catalysed dehydration of tertiary butyl alcohol faster than that of n-butyl alcohol?

    Answer:

                    Acidic dehydration of alcohol involves the formation of carbocation intermediate in a slow step. Since tertiary butylalcohol forms a tertiary butyl carbocation which is more stable than the n-butyl carbocation formed in case of n-butyl alcohol therefore, tertiary butyl alcohol is more reactive than n-butyl alcohol.
