Chapter 4, Problem 4.100QP

(a)

Interpretation Introduction

Interpretation: The oxidation number of nitrogen in each given molecules is to be stated.

Concept introduction: The oxidation state or number in a compound is the charge present on the individual atom if the all bonds are assumed to be ionic. The net charge present on a neutral compound is always zero. The charge present on the ionic compound is equal to the some of the charges of all the atoms present in that ionic compound.

To determine: The oxidation number of nitrogen in elemental nitrogen $\left({\text{N}}_{\text{2}}\right)$.

(b)

Interpretation Introduction

To determine: The oxidation number of nitrogen in hydrazine $\left({\text{N}}_{\text{2}}{\text{H}}_{\text{4}}\right)$.

(c)

Interpretation Introduction

To determine: The oxidation number of nitrogen in ammonium ion $\left({\text{NH}}_{\text{4}}{}^{+}\right)$.
