Chapter 5, Problem 5.7YT

Interpretation Introduction

Interpretation:

Using Lewis structure and VSEPR theory, the correct molecular geometry of ${\text{CF}}_2{\text{Cl}}_2$ is to be predicted.

Concept introduction:

The VSEPR (valence shell electron pair repulsion) theory is helpful in predicting the shapes of molecules from their Lewis structures.

The electron geometries of a molecule are determined on the basis of the total number of electron groups, the number of bonding groups and the number of lone pairs.

To determine the molecular geometry of a molecule, the Lewis structure is drawn and the electron groups are counted. On the basis of bonding groups, the molecular geometry is predicted.
