Vedclass · Answer

(A) The rate of dehydration of alcohols depends on the stability of the carbocation intermediate formed after the loss of water.$I$ is phenol,which forms a phenyl carbocation $(C_6H_5^+)$ upon dehydration. This is extremely unstable due to the $sp$ hybridization of the carbon atom.$II$ is cyclohexanol,which forms a $2^{\circ}$ alkyl carbocation.$III$ is cyclohex$-2-$en$-1-$ol,which forms an allylic carbocation. This is stabilized by resonance.$IV$ is cyclohexa$-2,5-$dien$-1-$ol,which forms a carbocation that is stabilized by resonance with two double bonds,making it the most stable among the given options.Comparing the stability of the carbocations: Phenyl carbocation $(I)$ Therefore,the correct order of dehydration is $I < II < III < IV$.

Among the given compounds,the correct dehydration order is:
