The major product formed in the following reaction is: i) Na/liquid NHs i) CaHgBr COOH Product COOH COOH (B) (A) CaHg Catte COOH CoOH (D) CaHs (C) CAHe
Option A is the correct answer as COOH is the electron withdrawing group and so in the birch reduction step negative charge will reside in the carbon attached to -COOH group.
Hence...
