Chapter 10, Problem 10.96QE

(a)

Interpretation Introduction

Interpretation:

Homonuclear diatomic molecule or ion that has the MO electronic configuration as ${({\sigma }_{2s})}^2{({\sigma }_{2s}^{*})}^2{({\pi }_{2p})}^4{({\sigma }_{2p})}^1$ has to be given and also the species is stable or not has to be found out.

Concept Introduction:

Homonuclear diatomic species contains two atoms from the same element.  MO electronic configuration uses the bonding and antibonding orbtitals.  Bond order can be used to find whether the species will be stable or not.  Bond order can be found out by the formula given below;

    $\begin{array}{l}\text{Bond}\text{order}=\frac{1}{2}(\text{number}\text{of}\text{electrons}\text{in}\text{bonding}\text{orbitals}\\ -\text{number}\text{of}\text{electrons}\text{in}\text{antibonding}\text{orbitals})\end{array}$
