Vedclass · Answer

(C) The presence of $P-H$ bonds in phosphorus oxyacids is determined by their structures:$1$. $H_3PO_4$ (Orthophosphoric acid): Contains three $P-OH$ bonds and one $P=O$ bond. No $P-H$ bond.$2$. $H_3PO_3$ (Phosphorous acid): Contains two $P-OH$ bonds,one $P=O$ bond,and one $P-H$ bond.$3$. $H_3PO_2$ (Hypophosphorous acid): Contains one $P-OH$ bond,one $P=O$ bond,and two $P-H$ bonds.Therefore,the pair $H_3PO_3$ and $H_3PO_2$ contains $P-H$ bonds.
