`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

The give structures cannot be taken as the canonical forms of the resonance hybrid of `H_(3)PO_(3)` because the positions of the atoms have changed.
