Chapter 4, Problem 4.55E

Interpretation Introduction

(a)

Interpretation:

The shape of the ${\text{NH}}_{\text{2}}^{-}$ by first drawing a Lewis structure, then applying the VSEPR theory is to be drawn.

Concept introduction:

Lewis structure is a representation of a chemical formula of substance with valance electrons of atoms. According to VSEPR theory, electron pairs in the valence shell of the central atom repel one another and try to minimize this repulsion by increasing their separation distance. This is done by forming bond between central atom and other atoms.

Interpretation Introduction

(b)

Interpretation:

The shape of the ${\text{PO}}_{\text{3}}^{\text{3}-}$ by first drawing a Lewis structure, then applying the VSEPR theory is to be drawn.
