The Correct Option is D

Solution and Explanation

The given chemical reaction involves the reduction of a diketone compound using the Clemmensen reduction method, which utilizes zinc amalgam (Zn-Hg) and concentrated hydrochloric acid (HCl). This reduction typically converts carbonyl groups (C=O) to methylene groups (CH2).

Let's break down the reaction step-by-step: 

  1. The starting compound is a diketone, having two carbonyl groups.
  2. In the Clemmensen reduction, the carbonyl oxygens are removed, and the carbonyl carbons are reduced to methylene groups.
  3. Thus, the carbonyl groups (C=O) are replaced by hydrogen atoms, resulting in the compound having CH2 groups where the carbonyl groups were.

This results in the formation of a hydrocarbon chain without the carbonyl groups, maintaining the original carbon backbone.

The product (A) is the reduced form of the given diketone. Below is the image of the correct product (A):

Therefore, the correct answer is the option that shows the conversion from the diketone to the corresponding di-methylene derivative.
