Chapter 9, Problem 11SAQ

Interpretation Introduction

Interpretation:

The formal charge of $\text{N}$ in the given structure is to be identified.

Concept introduction: A formal charge is the charge assigned to an atom in a molecule. It is assumed that electrons in all bonds are shared equally between atoms, regardless of relative electronegativity.

Formal charge is calculated by the formula,

$\text{Formal}\text{charge}=\left(\begin{array}{c}\text{Valence}\text{electrons}-\\ \left[\text{Lone}\text{pair}\text{electrons}+\frac{\text{Bonding}\text{electrons}}{2}\right]\end{array}\right)$

To determine: The formal charge of $\text{N}$ in the given structure.

Correct answer: The correct option is (a).
