The term nitrogen oxide typically refers to any binary compound of oxygen and nitrogen, or to a mixture of such compounds:
(Note that the last three are unstable.)
Chemical reactions that produce nitrogen oxides often produce several different compounds, the proportions of which depend on the specific reaction and conditions. For this reason, secondary[clarification needed] production of N2O is undesirable, as NO and NO2 — which are extremely toxic — are liable to be produced as well.
