Chemistry - Aromatic Hydrocarbon Question with Solution | TestHub

The given reaction is a Birch reduction of anisole using Na/liq. NH₃.

* The methoxy group (–OCH₃) acts as an electron-donating group (+M effect).

* For benzene rings with electron-donating groups, the reduction yields a non-conjugated 1,4-diene where the carbon bearing the substituent retains its double bond ($s{p}^2$ hybridized).

* Since the carbon attached to –OCH₃ must remain part of a double bond, Option (C) is the correct product (P).
