Vedclass · Answer

(D) Both $H_4P_4O_{12}$ (cyclotetrametaphosphoric acid) and $H_3P_3O_9$ (cyclotrimetaphosphoric acid) are cyclic metaphosphoric acids with the general formula $(HPO_3)_n$.In these cyclic structures,each phosphorus atom is bonded to one $OH$ group,one $P=O$ group,and two oxygen atoms that form the $P-O-P$ linkages in the ring.For $H_3P_3O_9$ $(n=3)$: It has $3$ $P=O$ bonds,$3$ $P-O-H$ bonds,and $3$ $P-O-P$ bonds.For $H_4P_4O_{12}$ $(n=4)$: It has $4$ $P=O$ bonds,$4$ $P-O-H$ bonds,and $4$ $P-O-P$ bonds.Since the number of bonds depends on the value of $n$,none of the options provided are identical for both molecules.

$H_4P_4O_{12}$ and $H_3P_3O_9$ have the same:
