Vedclass · Answer

(B) $1$. The reaction starts with cyclopentanone. Treatment with $HCN$ gives the cyanohydrin,which is $1$-hydroxycyclopentanecarbonitrile $(A)$.$2$. Reduction of the cyanohydrin $(A)$ with $LiAlH_4$ reduces the $-CN$ group to a $-CH_2NH_2$ group,yielding $1$-aminomethylcyclopentan$-1-$ol $(B)$.$3$. Treatment of the primary amine $(B)$ with $NaNO_2/HCl$ (diazotization) leads to the formation of a diazonium salt,which is unstable and undergoes a Tiffeneau-Demjanov rearrangement. This involves the expansion of the five-membered ring to a six-membered ring,resulting in the formation of cyclohexanone $(C)$.

The end product $(C)$ in the following reaction is:
