Chapter 20, Problem 20.28QP

Interpretation Introduction

Interpretation:

The Lewis structures for ${\text{CF}}_{\text{3}}{\text{CHCl}}_{\text{2}}$ and ${\text{CF}}_{\text{3}}{\text{CFH}}_{\text{2}}$ have to be drawn.

Concept Introduction:

Lewis-dot structure:

The sharing of electrons between atoms and forms covalent bonds. This structure denotes valence electrons of an atom by dots and also it shows the way of valence electron distributed within a molecule.
