Vedclass · Answer

(D) $1$. The reaction of the aldehyde with $NaCN$ and $H_2O$ (cyanohydrin formation) yields the cyanohydrin product $[A]$. The structure of $[A]$ is a $2$-hydroxy-$3$-methylhexanenitrile derivative.$2$. The reduction of the nitrile group $(-CN)$ in $[A]$ using $LiAlH_4$ produces a primary amine $(-CH_2NH_2)$. Thus, $[B]$ is the corresponding amino-alcohol.$3$. The acid-catalyzed hydrolysis of the nitrile group $(-CN)$ in $[A]$ using $HCl/H_2O$ and heat $(\Delta)$ converts it into a carboxylic acid group $(-COOH)$. Thus, $[C]$ is the corresponding hydroxy-acid.$4$. Comparing these structures with the given options, option $D$ correctly represents the structures of $[A]$, $[B]$, and $[C]$.

The structures of major products $A$, $B$, and $C$ in the following reaction sequence are:
