Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N 2 O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]
Dinitrogen oxide can potentially refer to any of at least four compounds: Dinitrogen monoxide (nitrous oxide), N 2 O Dinitrogen dioxide , N 2 O 2 , an unstable dimer of nitric oxide
Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen . Nitric oxide is a free radical : it has an unpaired electron , which is sometimes denoted by a dot in its chemical formula ( • N=O or • NO).
Since N 2 is isoelectronic with carbon monoxide (CO) and acetylene (C 2 H 2), the bonding in dinitrogen complexes is closely allied to that in carbonyl compounds, although N 2 is a weaker σ-donor and π-acceptor than CO.

Its molar mass is 92.011 g/mol. Dinitrogen tetroxide is a powerful oxidizer that is hypergolic (spontaneously reacts) upon contact with various forms of hydrazine, which has made the pair a common bipropellant for rockets.
Dinitrogen dioxide is an inorganic compound having molecular formula N 2 O 2.Many structural isomers are possible. The covalent bonding pattern O=N–N=O (a non-cyclic dimer of nitric oxide (NO)) is predicted to be the most stable isomer based on ab initio calculations and is the only one that has been experimentally produced.

Dinitrogen trioxide, however, has an unusually long N–N bond at 186 pm. Some other nitrogen oxides also possess long N–N bonds, including dinitrogen tetroxide (175 pm). The N 2 O 3 molecule is planar and exhibits C s symmetry. The dimensions displayed on the picture below come from microwave spectroscopy of low-temperature, gaseous N 2 O 3: [4]
