Chapter 8, Problem 102A

Interpretation Introduction

(a)

Interpretation:

Lewis structure of ${\text{PCl}}_{\text{5}}$ is needs to be explained.

Concept introduction:

Lewis structure is also called as Lewis dot structure. In this structure valance electrons are represented by dot symbol around the central atom. This structure shows the Bonding between molecule and the lone pairs which may occur in the molecule.

Answer to Problem 102A

The Lewis structure of ${\text{PCl}}_{\text{5}}$ is-

Explanation of Solution

Determine the valence electrons which are available for bonding in ${\text{PCl}}_{\text{5}}$. It contains one phosphorus and 5 chlorine atoms. Hence, total number of valance electron is $5+7\times 5=40$. Hence, P can hold more than 8 valence electrons. The Lewis structure of ${\text{PCl}}_{\text{5}}$is as follows:
