Chapter 9.7, Problem 9PE

Interpretation Introduction

Interpretation: The existence of ${\text{H}}_2{}^{+}$ using the MO theory is to be explained.

Concept introduction: The bond order is calculated by the formula,

$\text{Bond}\text{order}=\frac{\left(\begin{array}{l}\text{Number}\text{of}\text{electrons}\\ \text{in}\text{bonding}\text{molecular}\\ \text{orbitals}\end{array}\right)-\left(\begin{array}{l}\text{Number}\text{of}\text{electrons}\\ \text{in}\text{antibonding}\\ \text{molecular}\text{orbitals}\end{array}\right)}{2}$

Higher is the bond order, stronger is the bond.

To identify: The existence of ${\text{H}}_2{}^{+}$ using the MO theory.
