Vedclass · Answer

(D) The dehydration of alcohols follows the order of stability of the carbocation intermediate formed: $3^\circ > 2^\circ > 1^\circ$. In the case of $2-$ Phenyl $-2-$ butanol,the carbocation formed after the loss of the hydroxyl group is a tertiary $(3^\circ)$ carbocation. Furthermore,this carbocation is benzylic,meaning it is stabilized by resonance with the phenyl ring. This combination of being a tertiary carbocation and being resonance-stabilized makes the carbocation intermediate from $2-$ Phenyl $-2-$ butanol the most stable among the given options. Therefore,$2-$ Phenyl $-2-$ butanol undergoes dehydration most easily.
