Chapter 18, Problem 67E

Interpretation Introduction

Interpretation: The Lewis structure of two allotropes of oxygen needs to be determined. The paramagnetism of ${\text{O}}_2^{}$ molecule needs to be explained on the basis of molecular orbital model. Also, the molecular structure and bond angle of ozone molecule needs to be explained.

Concept Introduction:

Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Lewis dot structure is also known as Lewis dot formula or electron dot structure.

Molecular orbital theory explained the bonding, magnetic and spectral properties of molecule. It is based on the formation of molecular orbitals by the combination of atomic orbitals.

Molecular orbital diagrams represents the distribution of electrons in different molecular orbitals in increasing order of their energy. Hence lower energy molecular orbitals occupy first then only electron moves in higher energy orbitals.
