$1,2-$dimethylcyclohexene

Vedclass · Answer

(C) The reaction involves the acid-catalyzed hydration of $1-$methyl$-1-$vinylcyclopentane. $1$. Protonation of the double bond leads to the formation of a secondary carbocation. $2$. The five-membered ring undergoes ring expansion to form a more stable six-membered ring carbocation. $3$. This carbocation then undergoes rearrangement and elimination of a proton $(-H^+)$ to form the most stable alkene,which is $1,2$-dimethylcyclohexene. Thus,the major product is $1,2$-dimethylcyclohexene.
