Vedclass · Answer

(A) The dehydration of the given alcohol ($2$-methyl-$1$-phenylcyclohexan-$1$-ol) proceeds via the formation of a carbocation intermediate. $1$. Protonation of the hydroxyl group followed by the loss of water molecule generates a secondary carbocation at the $C-1$ position. $2$. This carbocation undergoes a $1,2$-hydride shift to form a more stable benzylic carbocation at the position adjacent to the phenyl group. $3$. Elimination of a proton from the adjacent carbon leads to the formation of the most stable alkene,which is $1$-phenyl-$3$-methylcyclohex-$1$-ene,due to conjugation with the phenyl ring and the presence of $3$ $\alpha$-hydrogens.

The major product obtained by the dehydration of the given alcohol is:
