Chapter 9, Problem 43E

Interpretation Introduction

Interpretation:

The Lewis structure and certain distinguish between covalent and ionic compounds for the molecules ${\text{BI}}_{\text{3}}\text{,}{\text{K}}_{\text{2}}\text{S,}\text{HCFO}$ and ${\text{PBr}}_{\text{3}}$ is to be drawn.

Concept introduction: The Lewis structure is a method of representation of the bonds and the number of lone pair electron in a molecule.

The main difference covalent and ionic compounds is that in the covalent compounds electrons are distributed equally between the bonded atoms where as in the ionic compounds electron cloud lies more towards the electronegative atom.

To determine: The Lewis structure and distinguish between covalent and ionic compounds for the molecules ${\text{BI}}_{\text{3}}\text{,}{\text{K}}_{\text{2}}\text{S,}\text{HCFO}$ and ${\text{PBr}}_{\text{3}}$
