Chapter 8, Problem 8.20A

Interpretation Introduction

Interpretation:

The bond order for the species ${\text{O}}_{\text{2}}{}^{2-},{\text{O}}_{\text{2}}{}^{-},{\text{O}}_{\text{2}},{\text{O}}_{\text{2}}{}^{+},{\text{O}}_{\text{2}}{}^{2+}$ needs to be determined and should be listed in order of increasing bond energy and increasing bond length.

Concept introduction:

The number of electrons involved in the formation of bonds in a molecule determines the bond order. The stability of a chemical bond is determined by the bond order. The bond order is inversely proportional to bond length thus, bond order increases if bond length decreases.
