The Clemmensen reduction utilizes Zn-Hg and HCl to convert carbonyl groups, such as those in aldehydes and ketones, into methylene (-CH2-) groups.
The initial compound is expected to contain a carbonyl (C=O) group. This group will undergo reduction to a -CH2- group when subjected to Zn-Hg and HCl.
Applying the principles of the Clemmensen reduction, the resultant product will exhibit a methylene (-CH2-) group in place of the original carbonyl group. Option (4) visually depicts this transformation where the carbonyl group has been reduced to a -CH2- group.
The correct representation of the reaction product is found in Option (4).
