Question

Give the structure of X and Y:

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

When using BH3 in the reduction of carbonyl compounds, the product is typically a secondary alcohol, which undergoes further oxidation with H2O2 and OH−.

Answer 1

The Correct Option is A

In this reaction, \( \text{BH}_3 \) reacts with X (a carbonyl group) to reduce the carbonyl group to a secondary alcohol. Then, further reaction with \( \text{H}_2\text{O}_2 \) and \( \text{OH}^- \) converts the alcohol group to a hydroxy group, leading to the product Y.
