Question:
H₃PO₃ can be represented by structures 1 and 2 shown below. Can these two structures be taken as the canonical forms of the resonance hybrid representing H₃PO₃? If not, give reasons for the same.

Answer:

The most favourable condition for writing resonating structures is that the different resonating structures must have same position of atoms.

Here in the given example the H atom has changed its position in the second structure as compared to first, therefore these two structures cannot be considered as the resonating structures for the given compound.
