Vedclass · Answer

(D) The reaction involves the nucleophilic addition of $HCN$ to acetaldehyde $(CH_3CHO)$.The carbonyl carbon in $CH_3CHO$ is $sp^2$ hybridized and planar.The cyanide ion $(CN^-)$ can attack the carbonyl carbon from either the top or the bottom face with equal probability.This leads to the formation of a racemic mixture of the cyanohydrin intermediate,which upon hydrolysis yields a racemic mixture of $2$-hydroxypropanoic acid (lactic acid).$A$ racemic mixture consists of an equal amount of $D$ and $L$ isomers,i.e.,a $(50\% \,D + 50\% \,L)$ mixture.

In the reaction,the acid obtained will be
$CH_3CHO + HCN \to CH_3CH(OH)CN \xrightarrow{H_2O} CH_3CH(OH)COOH$
