  2. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    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.

  3. Trinitrogen - Wikipedia

    en.wikipedia.org/wiki/Trinitrogen

    [2] [3] The linear form of N 3 was discovered in 1956 by B. A. Thrush [4] by photolysis of hydrogen azide. [5] As a linear and symmetric molecule, it has D ∞h symmetry, with a nitrogen–nitrogen bond length averaging 1.8115 Å. The first excited electronic state, A 2 Σ u, is 4.56 eV above the ground state.

  4. Heterocyclic compound - Wikipedia

    en.wikipedia.org/wiki/Heterocyclic_compound

    A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [1] Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles .

  5. IUPAC nomenclature of chemistry - Wikipedia

    en.wikipedia.org/.../IUPAC_nomenclature_of_chemistry

    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.

  7. Nitride - Wikipedia

    en.wikipedia.org/wiki/Nitride

    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.

  8. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1] [2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3]

  9. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    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.
