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.
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
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).
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 cation is always named first. Ions can be metals, non-metals or polyatomic ions. Therefore, the name of the metal or positive polyatomic ion is followed by the name of the non-metal or negative polyatomic ion. The positive ion retains its element name whereas for a single non-metal anion the ending is changed to -ide.
Fenestranes A class of compounds with astructural formula that resembles a "window pane motif" (the name fenestrane derives from the Latin word fenestra, meaning window), comprising four fused carbocycles centred on a quaternary carbon resulting in a twice-over spiro compound. The illustration at right shows a generic fenestrane as well as the ...
The general rule is to use the name most commonly used to refer to the compound, as evidenced by use in reliable sources (in line with WP:COMMONNAME). Classes of compounds may have more specific guidance on naming, such as the use of international nonproprietary names for pharmaceutical compounds (see WP:NCMED and below).
substitutive naming based on parent hydrides (GeCl 2 Me 2 dichlorodimethylgermane) additive naming ([MnFO 3] fluoridotrioxidomanganese) Additionally there are recommendations for the following: naming of cluster compounds; allowed names for inorganic acids and derivatives; naming of solid phases e.g. non-stoichiometric phases
