Vedclass · Answer

(D) The acid-catalyzed dehydration of $1$-cyclohexylbutan-$1$-ol proceeds via an $E1$ mechanism:$1$. Protonation of the $-OH$ group followed by the loss of water generates a secondary carbocation at the $C1$ position of the side chain.$2$. This carbocation can undergo rearrangement or direct elimination.$3$. Elimination of a proton from $C2$ gives $1$-cyclohexylbut-$1$-ene (Option $A$).$4$. Elimination of a proton from $C3$ gives $1$-cyclohexylbut-$2$-ene (Option $B$).$5$. Elimination of a proton from the cyclohexane ring (at the $C1$ position of the ring) gives $1$-butylcyclohexene (Option $C$).$6$. The structure $1$-cyclohexylidenebutane (Option $D$) would require the double bond to be between the cyclohexane ring and the side chain, which is not possible as the side chain is attached to the ring via a single bond and the carbocation is on the side chain, not the ring junction carbon. Thus, Option $D$ is not a product.
