Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

Question Explanation:  

The question asks for the major product formed when benzoic acid undergoes reduction using lithium in liquid ammonia.

Concept: This question is based on Birch Reduction. 

Solution:

In the Birch Reduction, benzoic acid contains an electron-withdrawing group (–COOH), which directs the reduction to occur at the ipso and para positions. This results in the formation of a non-conjugated 1,4-cyclohexadiene derivative where the carbon attached to the carboxylic group is reduced.
