Problem: Does a chlorate ion have resonance structures?

FREE Expert Solution

We are asked to determine if chlorate ion has a resonance structure


• Chlorate ion is a polyatomic anion with a formula ClO3-

Recall:

          • the suffix ‘ide’ is used to refer to monoatomic anions

          • the suffix ‘ite’ is used to refer to oxyanion with the lower oxidation state

          • the suffix ‘ate’ is used to refer to the oxyanion in the higher oxidation state


First, we must draw the  Lewis structure for ClO3-

• We need to determine the total number of valence electrons present:

ClO3-

           Group            Valence Electrons

Cl       7A                   1 × 7 e = 7 e

O        6A                   3 × 6 e = 18 e

                                + 1 e-

Total:  26 valence e
