Question

Which of the following does not undergo benzoin condensation?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Benzoin condensation is performed by aromatic aldehydes (i.e., compounds in which $-CHO$ group is directly attached with benzene ring).
In Benzoin condensation, aromatic aldehyde reacts with alcoholic $KCN$ to form benzoin product.
Hence, option (a) does not give benzoin condensation.
