Chapter 18, Problem 72E

Interpretation Introduction

Interpretation: The bonding in ${\text{SO}}_2^{}$ and ${\text{SO}}_3^{}$ with the help of localized electron model needs to be explained, also the p-bonding with the help of molecular orbital model for both compounds 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 exist 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.
