Chapter 9, Problem 9.89QP

Interpretation Introduction

Interpretation: The overlapping of two $\text{1s}$ orbitals to form a ${\text{σ}}_{\text{1s}}$ bonding molecular orbital and a ${\text{σ}}_{\text{1s}}^{\text{*}}$ antibonding molecular orbital is to be sketched.

Concept introduction: When two atomic orbitals come close to each other they lose their identity and form new pair of orbitals knows as molecular orbitals. Among the two molecular orbitals formed one has energy lower than the atomic orbitals is known as bonding molecular orbital and the other has energy higher than the atomic orbitals and is known as antibonding molecular orbital.

To determine: the sketch of the overlapping of two $\text{1s}$ orbitals to form a ${\text{σ}}_{\text{1s}}$ bonding molecular orbital and ${\text{σ}}_{\text{1s}}^{\text{*}}$ antibonding molecular orbital.
