Chapter 4, Problem 3ALQ

Interpretation Introduction

Interpretation: The comparison between Figure 4-47 and 4-49 is to be done and the reason for the difference between them is to be stated. The given statement about ${\text{B}}_{\text{2}}$ is to be rationalized. The reason for ${\sigma }_{2p}$ to be lower in energy than the ${\text{π}}_{2p}$ orbital is to be stated. The reason for not using diatomic oxygen for check this difference is to be sated.

Concept introduction: When the atomic orbitals overlap with each other in the region where density of electrons is high, then molecular orbitals are formed. Overlap of the atomic orbitals determines the efficiency of the interaction between the atomic orbitals.

Energy of bonding molecular orbitals is less than the nonbonding molecular orbitals.

To determine: The comparison between Figure 4-47 and 4-49, the reason for the difference between them, the rationalization of the given statement about ${\text{B}}_{\text{2}}$ , reason for ${\sigma }_{2p}$ to be lower in energy than the ${\text{π}}_{2p}$ orbital and reason for not using diatomic oxygen for check this difference.
