Vedclass · Answer

(C) The given reactant is a vicinal diol (pinacol). In the presence of an acid catalyst $(H^+)$,it undergoes a pinacol-pinacolone rearrangement. $1$. Protonation of one of the hydroxyl groups occurs. $2$. Loss of water leads to the formation of a carbocation. $3$. $A$ $1,2-$alkyl shift occurs to stabilize the carbocation and form a more stable oxocarbocation. $4$. Deprotonation yields the final ketone product. Given the structure,the migration of the ethyl group $(Et)$ is preferred over the methyl group $(Me)$ due to its higher migratory aptitude. Thus,the product is the ketone where the $Et$ group has shifted,resulting in the structure shown in option $C$.
