Chapter 10, Problem 10.9P

Interpretation Introduction

Interpretation:

The strength of the bond in ${\text{H}}_2{}^{+}$ compared to that in ${\text{H}}_2$ is to be identified.

Concept introduction:

The number of bonds between the pair of atoms is called bond order.
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.
