`H_(3)PO_(3)` can be represented by structure (a) and (b) shown below. Can these two structures be taken as the canonical forms of the resonance hybrid representing `H_(3)PO_(3)` ?If not, give reasons for the same.

Explanation

No. The structures (a) and (b) cannot be taken as the canonical forms of the resonance hybrid representing `H_(3)PO_(4)`, because the positions of atoms have been changed.
