Chapter 5, Problem 5.6YT

Interpretation Introduction

Interpretation:

Using the Lewis structure and VSEPR theory, the electron geometry and molecular geometry of ${\text{PCl}}_{\text{3}}$ are to be predicted.

Concept introduction:

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

The electron and molecular 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.
