Chapter 14, Problem 2DQ

Interpretation Introduction

Interpretation:

The difference between the $\sigma \text{ and }\pi \text{ MOs}$ for homonuclear diatomic molecules, needs to be explained.

The difference between bonding orbitals and antibonding orbitals needs to be identified. The reason for two $\pi$ MOs , one $\sigma$ MO and $\pi$ MO degenerate needs to be identified.

Concept Introduction :

The wave nature of electrons is assumed by molecular orbital theory, so through the overlapping the wave functions of dissimilar atoms interact in two ways- Constructive interreference and Destructive interference. The molecules possessing higher number of bonding electrons are more stable.
