Chapter 8, Problem 8.87QP

Interpretation Introduction

Interpretation: The Lewis structures for ${\text{H}}_{\text{2}}\text{NCN}$ is to be drawn and the preferred structure on the basis of formal charges is to be stated.

Concept introduction: Formal charge is calculated by the formula,

$\text{Formal}\text{charge}=\text{Valence}\text{electrons}-\left(\text{Lone}\text{pair}\text{electrons}+\frac{1}{2}\text{Bond}\text{pair}\text{electrons}\right)$

To determine: The Lewis structure for ${\text{H}}_{\text{2}}\text{NCN}$ and the preferred structure on the basis of formal charges.
