Vedclass · Answer

(D) The oxidation states of phosphorus $(P)$ in the given oxoacids are calculated as follows:$1$. For $H_4P_2O_5$ (Pyrophosphorous acid): The structure contains $P-O-P$ linkage. Each $P$ atom is bonded to two $OH$ groups and one $O$ atom. The oxidation state of $P$ is $+3$.$2$. For $H_4P_2O_6$ (Hypophosphoric acid): The structure contains $P-P$ linkage. Each $P$ atom is bonded to two $OH$ groups,one $O$ atom,and the other $P$ atom. The oxidation state of $P$ is $+4$.$3$. For $H_4P_2O_7$ (Pyrophosphoric acid): The structure contains $P-O-P$ linkage. Each $P$ atom is bonded to two $OH$ groups and two $O$ atoms (one double-bonded). The oxidation state of $P$ is $+5$.Thus,the oxidation states are $+3, +4, +5$ respectively.
