Chemical nomenclature is a set of rules to generate systematic names for chemical compounds. The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC Nomenclature ensures that each compound (and its various isomers) have only one formally accepted ...
The Geneva Nomenclature of 1892 was created as a result of many other meetings in the past, the first of which was established in 1860 by August Kekulé. Another entity called the International Association of Chemical Societies (IACS) existed, and on 1911, gave vital propositions the new one should address: [2]
Names of oxyanions should in general follow the names in Table X of the IUPAC 2005 Red Book. [2] Exceptions can be made if an alternate name is much more common in the literature, e.g. xenate rather than xenonate (don't generalise this to radon though, as it would create an ambiguity between radon and radium).
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound.The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
Even for elements such as nitrogen having only one stable allotrope, a name such as dinitrogen may be used to indicate its molecular structure N 2 as well as its elemental composition. The naming of chemical compounds comprising more than one element is a complex subject, discussed at length in the article on chemical nomenclature.
Chemical substance – Form of matter; Inorganic compounds by element; List of alloys; List of alkanes; List of elements by name; List of minerals – List of minerals with Wikipedia articles; List of alchemical substances; Polyatomic ion – Ion containing two or more atoms; Exotic molecules – Atoms composed of exotic particles can form ...
The element mercury was named after the Roman god of the same name (painting by Hendrik Goltzius). In chemistry, a trivial name is a non-systematic name for a chemical substance. That is, the name is not recognized according to the rules of any formal system of chemical nomenclature such as IUPAC inorganic or IUPAC organic nomenclature.
