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.

Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.
A demonstration that how some well known 1,3-dipoles like ozone, nitro compounds and azides can be shown to have a resonance structure having 1,3 relationship between positive and negative formal charges. Known 1,3-dipoles are: Azides (RN 3) Ozone (O 3) Nitro compounds (RNO 2) Diazo compounds (R 2 CN 2) Some oxides. Azoxide compounds (RN(O)NR)
Azide is isoelectronic with carbon dioxide CO 2, cyanate OCN −, nitrous oxide N 2 O, nitronium ion NO + 2, molecular beryllium fluoride BeF 2 and cyanogen fluoride FCN. Per valence bond theory, azide can be described by several resonance structures; an important one being N − =N + =N −.
Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure ...
Nitrogen dioxide is a chemical compound with the formula NO 2.One of several nitrogen oxides, nitrogen dioxide is a reddish-brown gas.It is a paramagnetic, bent molecule with C 2v point group symmetry.
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).
NO y (or NOy) refers to the sum of NO x and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NO x, HNO 3, HNO 2, etc.) NO z (or NOz) = NO y − NO x; Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.
