Vedclass · Answer

(A) The reaction shows the removal of the diazonium group $(-N_{2}^{+}Cl^{-})$ and its replacement with a hydrogen atom $(H)$.This is a reductive deamination reaction.$H_{3}PO_{2}$ (hypophosphorous acid) in the presence of water is the standard reagent used to reduce diazonium salts to the corresponding arene.The reaction is: $Ar-N_{2}^{+}Cl^{-} + H_{3}PO_{2} + H_{2}O \rightarrow Ar-H + N_{2} + H_{3}PO_{3} + HCl$.Therefore, the correct reagent is $H_{3}PO_{2}$.
