Chapter 9, Problem 9.6VP

Interpretation Introduction

Interpretation: More stability of ${\text{I}}_{\text{2}}^{\text{+}}$ than ${\text{I}}_{\text{2}}^{-}$ is to be explained using molecular orbital diagram.

Concept introduction: When two atomic orbitals of two atoms come close to each other they lose their identity and form new set of orbitals known as molecular orbitals.

This results in formation of two molecular orbitals, one bonding and other antibonding molecular.

Antibonding molecular has higher energy as compared to bonding molecular orbital.

To determine: The explanation for more stability of ${\text{I}}_{\text{2}}^{\text{+}}$ than the ${\text{I}}_{\text{2}}^{-1}$ on the basis of molecular diagram.
