Question

Product is:

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The Correct Option is B

The reaction follows the process of reduction and hydrolysis. Let's break it down step by step:
Step 1: Reduction by NaBH₄.
Sodium borohydride (NaBH\(_4\)) is used for reducing carbonyl groups. The reaction involves the reduction of an amide (or possibly a nitrile) to the corresponding amine. Therefore, the first step reduces a carbonyl group to an alcohol.
Step 2: Reaction with aqueous NaOH.
The second step involves treatment with aqueous NaOH (\(\Delta\)), which induces hydrolysis. This step would convert any remaining amide group into a carboxylic acid group.
Step 3: Acidic hydrolysis.
The final step involves acidic hydrolysis (H\(_2\)O\(^+\)), which typically works on ester or carboxylate salts, leading to the formation of an alcohol or an acid. Thus, the product formed corresponds to the structure in option (B), which contains both an alcohol and a carboxylic acid group. Final Answer: (B)
