Vedclass · Answer

(A) The reaction involves the acid-catalyzed dehydration of an alcohol. $1$. Protonation of the hydroxyl group occurs to form a good leaving group $(-OH_2^+)$. $2$. Loss of water generates a secondary carbocation. $3$. $A$ ring expansion occurs because the five-membered ring with a carbocation adjacent to it is less stable than a six-membered ring. The bond from the ring shifts to the carbocation center,resulting in a more stable six-membered ring with a carbocation at the adjacent position. $4$. Finally,deprotonation occurs to form the most stable alkene,which is the more substituted alkene (Saytzeff product). Thus,the major product is $1,2$-dimethylcyclohexene.
