A number of molecules and polyatomic ions cannot be described accurately by a single Lewis structure and a number of descriptions based on the same skeletal structure are written and these taken together represent the molecule or ion. These structures have almost similar energies, same arrangement of atoms, and have same number of bonding and non-bonding pair of electrons. These contributing structures or canonical forms taken together constitute the resonance hybrid which represents the molecule or ion.

The value of bond order of \( \mathrm{C}-\mathrm{O} \) bond for \( \mathrm{CO}_{3}^{2-} \) ion is:
(a) \( 1.25 \)
(b) \( 1.33 \)
(c) \( 1.5 \)
(d) \( 1.0 \)
