Chapter 12, Problem 71E

Interpretation Introduction

Interpretation:

The electron pair geometry, the molecular shape, and the bond angle for a silane molecule, ${\text{SiH}}_{\text{4}}$, is to be predicted using VSEPR theory.

Concept introduction:

The VSEPR theory is used to predict the shape of the molecule. It stands for valence shell electron repulsion theory. According to VSEPR theory, the central atom is surrounded by bonding and nonbonding electron pairs. The arrangement of electron pairs around the central atom is termed as the electron pair geometry. The arrangement of atoms is termed as the molecular shape. The angle between the two atoms bonded to the central atom is termed as the bond angle.
