Vedclass · Answer

(B) The correct option is $(B)$.The reaction involves the removal of the diazonium group $(-N_2^+ Cl^-)$ from the benzene ring and its replacement with a hydrogen atom.This transformation is achieved using hypophosphorous acid $(H_3PO_2)$ in the presence of water. The diazonium salt is reduced to the corresponding arene,while $H_3PO_2$ is oxidized to phosphorous acid $(H_3PO_3)$.The reaction is represented as:$Ar-N_2^+ Cl^- + H_3PO_2 + H_2O \rightarrow Ar-H + N_2 + H_3PO_3 + HCl$This is a standard method for the deamination of aromatic amines via their diazonium salts.

For the transformation shown below,the reagent used is:
