Vedclass · Answer

(B) The reducing property of phosphorus oxoacids is primarily determined by the number of $P-H$ bonds present in the molecule.$H_3PO_2$ (hypophosphorous acid) contains two $P-H$ bonds.$H_3PO_3$ (phosphorous acid) contains one $P-H$ bond.$H_3PO_4$ (phosphoric acid) contains zero $P-H$ bonds.$H_4P_2O_7$ (pyrophosphoric acid) contains zero $P-H$ bonds.Since $H_3PO_2$ has the maximum number of $P-H$ bonds,it acts as the strongest reducing agent among the given options.
