Vedclass · Answer

(A) To determine which oxoacids contain $P-O-P$ bonds, we examine their structures:$I$. $H_4P_2O_5$ (Pyrophosphorous acid): Contains a $P-O-P$ linkage.$II$. $H_4P_2O_6$ (Hypophosphoric acid): Contains a $P-P$ bond, not $P-O-P$.$III$. $H_4P_2O_7$ (Pyrophosphoric acid): Contains a $P-O-P$ linkage.$IV$. $(HPO_3)_3$ (Cyclotrimetaphosphoric acid): Contains a cyclic structure with $P-O-P$ linkages.Therefore, $I$, $III$, and $IV$ all contain $P-O-P$ bonds. Given the options provided, both $A$ ($III$ and $IV$) and $C$ ($I$ and $III$) contain correct examples, but $I$, $III$, and $IV$ are the complete set.
