acetaldehyde

Vedclass · Answer

(B) . Acetaldehyde $(CH_3CHO)$ reacts with $HCN$ to form acetaldehyde cyanohydrin $(CH_3CH(OH)CN)$.On hydrolysis,it yields lactic acid $(CH_3CH(OH)COOH)$.Since the $\alpha$-carbon in lactic acid is chiral (bonded to four different groups: $-H$,$-OH$,$-CH_3$,and $-COOH$),it exists as a racemic mixture when synthesized from an achiral starting material like acetaldehyde.

$A$ carbonyl compound reacts with hydrogen cyanide $(HCN)$ to form cyanohydrin,which on hydrolysis forms a racemic mixture of $\alpha$-hydroxy acid. The carbonyl compound is:
