Question

What are X and Y respectively in the following reactions? 

• A.
• B.
• C.
• D.

Hint:

DIBAL-H is a strong reducing agent commonly used to reduce carboxylic acids to aldehydes.

Answer 1

The Correct Option is C

In the reaction, the compound \( {C}_6{H}_5{COOH} \) (Benzoic Acid) reacts with a reducing agent to form the corresponding aldehyde.
- Step 1: The reaction of \( {C}_6{H}_5{COOH} \) with DIBAL-H (Diisobutylaluminum hydride) leads to the reduction of the carboxyl group (\( {COOH} \)) to an aldehyde group (\( {CHO} \)).
- Step 2: The addition of water \( {H}_2{O} \) hydrolyzes the intermediate to yield the desired product.
Thus, X is DIBAL-H and Y is the aldehyde formed from the reduction of benzoic acid.
Therefore, the correct answer is option (3).
