${{\rm{H}}_3}{\rm{P}}{{\rm{O}}_3}$ can be represented by structure $1$ and $2$ shown below. Can these two structures be taken as the canonical forms of the resonance hybrid representing ${{\rm{H}}_3}{\rm{P}}{{\rm{O}}_3}$ ? If not, give reasons for the same.

These two structure cannot taken as the canonical forms of the resonance hybrid. Because the position of nucleus of atom is change. In resonance form the position of nucleus is not changed.
