Chapter 9, Problem 9.63QP

Interpretation Introduction

Interpretation: The complete Lewis structure of given compound is to be identified, also the formal charge on the highlighted atoms is to be calculated and the description of bonding around the highlighted atoms is to be stated.

Concept introduction: The Lewis structure represents all bonding and non-bonding electrons surrounding the atoms involved in a molecule. A molecule exhibits a particular geometry in space considering the steric hindrances of the bond pairs and the lone pairs of electron.

The formal charge is calculated by the formula,

$\text{Formal}\text{charge}=\left[\begin{array}{r}\left(\text{Number}\text{of}\text{valence}\text{electrons}\right)-\\ \left(\begin{array}{l}\text{Number}\text{of}\text{non}\text{bonding}\text{electrons}\\ \text{around}\text{the}\text{atom}\end{array}\right)-\\ \frac{1}{2}\left(\begin{array}{l}\text{Number}\text{of}\text{bonding}\text{electrons}\\ \text{around}\text{the}\text{atom}\end{array}\right)\end{array}\right]$

To determine: The complete Lewis structure of given compound, formal charge on the highlighted atoms and the description of bonding around the highlighted atoms.
