Chapter 9, Problem 9.98QP

Interpretation Introduction

Interpretation:

The Lewis structure for given set of compounds namely $CFC{l}_3$, $C{F}_{2}C{l}_2$, $CH{F}_{2}Cl$ and $C{F}_{3}CH{F}_2$ should be drawn.

Concept Introduction:

The chemical bonding present in covalently bonded molecules and in coordination compounds are represented using Lewis structures.

Electron dot structure also known as Lewis dot structure represents the number of valence electrons of an atom or constituent atoms bonded in a molecule. Each dot corresponds to one electron.

Lewis structure for any molecule is drawn by using the following steps,

First the skeletal structure for the given molecule is drawn then the total number of valence electrons for all atoms present in the molecule is determined

The next step is to subtract the electrons present in the total number of bonds present in the skeletal structure of the molecule with the total valence electrons such that considering each bond contains two electrons with it.

Finally, the electrons which got after subtractions have to be equally distributed such that each atom contains eight electrons in its valence shell.
