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




No, the structures 1 and 2 cannot be taken as canonical forms because the position of atoms has been changed.


While making resonating structures, following conditions must be followed:


We cannot change the position of any atom. Atoms must be in their own position.


We can only shift the bonds from one atom to another.


We can only change the position of electrons from one atom to another.
