Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Question Explanation:

The question asks to identify the major product formed when anisole (methoxybenzene) reacts with sodium in liquid ammonia.

Concept:

This question is based on Birch Reduction. 

Solution:  

In a Birch Reduction, an electron-donating group like -OCH₃ directs the reduction such that the carbon attached to the group remains substituted and is not reduced. The resulting product is a 1,4 cyclohexadiene where the double bonds are not conjugated with the substituent .
