The cyclic form was identified in 2003 by N. Hansen and A. M. Wodtke using ultraviolet photolysis of chlorine azide. Although the reaction yielded mostly the linear form, about 20% of the molecules were cyclic. [4] [1] The ring has C 2v symmetry [1] —an isosceles triangle—in contrast to the linear form that has equal N–N bond-lengths.
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.
The main structure of chemical names according to IUPAC nomenclature. IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.

Where an acid has both a systematic and a common name (like CH 3 COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name. Thus, KCH 3 CO 2 can be named as potassium acetate or as potassium ethanoate. The prefix form, is "carboxylato-".
In chemistry, a nitride is a chemical compound of nitrogen.Nitrides can be inorganic or organic, ionic or covalent.The nitride anion, N 3-ion, is very elusive but compounds of nitride are numerous, although rarely naturally occurring.
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
