Question

Which of the following does not undergo benzoin condensation?

• A. A
• B. B
• C. C
• D. D

Hint:

Benzoin condensation typically occurs with aromatic aldehydes but does not work with aldehydes containing electron-donating groups.

Answer 1

The Correct Option is A

Step 1: Understanding benzoin condensation.
Benzoin condensation is a reaction between aldehydes in the presence of a catalyst. Certain functional groups on aldehydes, like the presence of \( \text{CH}_3 \), prevent them from undergoing benzoin condensation.

Step 2: Conclusion.
\( \text{CH}_3\text{CHO} \) does not undergo benzoin condensation, which corresponds to option (1).
