Question

The product formed in the following chemical reaction is:

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is A

To determine the product formed in the given chemical reaction, we need to analyze the reaction conditions and the given compound.

The reaction involves the reduction of a keto group using sodium borohydride (\( \text{NaBH}_4 \)) in ethanol (\( \text{C}_2\text{H}_5\text{OH} \)). Sodium borohydride is a selective reducing agent that primarily reduces aldehydes and ketones to alcohols.

The structure of the reactant is given as:

In this compound, the carbonyl group (C=O) is present as a ketone. Sodium borohydride will reduce this ketone group to a secondary alcohol by adding hydrogen across the C=O bond.

Let's analyze what the product will look like:

1. The carbonyl group (C=O) gets reduced to a hydroxyl group (C-OH).
2. The rest of the compound remains unchanged as NaBH₄ is a selective reducing agent and does not alter other functional groups in this context.

Hence, the ketone is reduced to a secondary alcohol.

Therefore, the product of the reaction is:

This is the correct answer because it shows the formation of a secondary alcohol from the reduction of the ketone group.
