Chapter 4, Problem 82E

Interpretation Introduction

Interpretation: The bonding in ${\text{CO}}_3{}^{2-}$ is to be described using the localized electron model and molecular orbital model.

Concept introduction: The valence bond theory is based on the assumption that all the bonds present between two atoms are localized bonds formed by the donation of an electron from each atom. The localized electron model consists of the following,

• The Lewis structure is drawn.
• The arrangement of the electron pairs is determined.
• The required hybrid orbitals are specified.

The $\text{π}$ bonding for multi-electron atom can be described using the molecular orbitals.

To determine: Bonding in ${\text{CO}}_3{}^{2-}$ on the basis of the localized electron model and molecular orbital model.
