Question

A carbonyl compound reacts with hydrogen cyanide to form cyanohydrin which on hydrolysis forms a racemic mixture of α-hydroxy acid. The carbonyl compound is (A) acetaldehyde (B) acetone (C) diethyl ketone (D) formaldehyde

Tardigrade Admin · Accepted Answer

Acetaldehyde reacts with hydrogen cyanide ( HCN ) to form cyanohydrin ( CH 3 CH ( OH ) CN ) which on hydrolysis forms a racemic mixture of α - hydroxy acid ( CH 3 CH ( OH ) COOH ) As the cyanohydrin of acetaldehyde contains chiral centre so we will get racemic mixture.

Q. A carbonyl compound reacts with hydrogen cyanide to form cyanohydrin which on hydrolysis forms a racemic mixture of $α$ -hydroxy acid. The carbonyl compound is

acetaldehyde

acetone

diethyl ketone

formaldehyde

Acetaldehyde reacts with hydrogen cyanide $(H CN)$ to form cyanohydrin $(C H_{3} C H (O H) CN)$ which on hydrolysis forms a racemic mixture of $α$ - hydroxy acid $(C H_{3} C H (O H) COO H)$ As the cyanohydrin of acetaldehyde contains chiral centre so we will get racemic mixture.
