Vedclass · Answer

(B) Dehydration of alcohols proceeds via the formation of a carbocation (carbonium ion). The stability of carbocations follows the order: $3^\circ > 2^\circ > 1^\circ$. $1.$ Option $(a)$ is a primary alcohol and forms a $1^\circ$ carbocation: $CH_3-CH(CH_3)-CH_2^+$. $2.$ Option $(b)$ is a tertiary alcohol and forms a $3^\circ$ carbocation: $(CH_3)_3C^+$. $3.$ Option $(c)$ is a primary alcohol and forms a $1^\circ$ carbocation: $CH_3-CH_2-CH_2-CH_2^+$. $4.$ Option $(d)$ is an alkane and does not undergo dehydration in this context. Since the $3^\circ$ carbocation is the most stable,tert-butyl alcohol (Option $B$) is the correct answer.

The compound which gives the most stable carbonium ion on dehydration is
