Chapter 10, Problem 10.17QP

Interpretation Introduction

Interpretation:

The bond angle of $\text{H-P-H}$ in ${\text{PH}}_{\text{3}}$ has to be given with the help of valence bond theory.

Concept Introduction:

Valence bond theory: VSEPR theory tells about the shapes of molecules and ions by taking the consideration that the outermost electron pairs are arranged about each atom so that the pairs of electrons are kept at a distance from one molecule to other, thereby minimizing the repulsion of electron-pair.

To identify the bond angle of $\text{H-P-H}$ in ${\text{PH}}_{\text{3}}$
