Isobutyraldehyde on reaction with formaldehyde and K_2CO_3 gives compound 'A'. Compound 'A' reacts with KCN and yields compound 'B', which on hydrolysis gives a stable compound 'C'. The compound 'C' is

MARKS Content Team · Accepted Answer

Correct answer: (C). In the first step formaldehyde undergoes cross aldol reaction with isobutyraldehyde to form (A)and then the product(A) forms cyanohydrin (B)with KCN, which on hydrolysis forms a compound containing carboxylic acid group and finally this molecule undergoes intramolecular esterification to form (C) a stable compound.
