Introduction

Occurence and Properties of the Element

Nitrides

Hydrides

Ammonia

Hydrazine

Hydoxylamine

Hydroxylamine, NH2OH, is a weak base and is used as a reducing agent.

Azides

The azide ion, N3, is derived from the unstable (explosive) hydrazoic acid HN3. It is a pseudo halide.

Nitrogen Monoxide (Nitric Oxide)

Nitrogen Dioxide and Dinitrogen Tetroxide

Dinitrogen Trioxide

Dinitrogen Pentoxide

The Nitronium Ion

Nitrous Acid

Summary of Reaction and Interconversions Among the Oxides, Oxo Acids and Oxo Anions of Nitrogen

These species and many of their interconversions are of considerable industrial and environmental importance:
