Nitrogen oxide

Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds:

Charge-neutral

Nitric oxide (NO), nitrogen(II) oxide, or nitrogen monoxide
Nitrogen dioxide (), nitrogen(IV) oxide
Nitrogen trioxide (), or nitrate radical
Nitrous oxide (), nitrogen(0,II) oxide
Dinitrogen dioxide (), nitrogen(II) oxide dimer
Dinitrogen trioxide (), nitrogen(II,IV) oxide
Dinitrogen tetroxide (), nitrogen(IV) oxide dimer
Dinitrogen pentoxide (), nitrogen(V) oxide, or nitronium nitrate
Nitrosyl azide (), nitrogen(−I,0,I,II) oxide

Stability

Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to and , which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.
