The rest are named with a Greek numeric prefix, with the exceptions of nonane which has a Latin prefix, and undecane which has mixed-language prefixes. Cyclic alkanes are simply prefixed with "cyclo-": for example, C 4 H 8 is cyclobutane (not to be confused with butene ) and C 6 H 12 is cyclohexane (not to be confused with hexene ).
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.
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 ]
Articles about functional groups should use the name most commonly used to refer to the group in reliable sources (generally, the name of the corresponding radical) followed by the word "group", e.g. alkyl group, carboxyl group, phenyl group, carbonyl group, trimethylsilyl group, triflyl group. In many cases, the compound or compound class and ...

Numerical prefixes for multiplication of compound or complex (as in complicated) features are created by adding kis to the basic numerical prefix, with the exception of numbers 2 and 3, which are bis- and tris-, respectively.
In chemistry, a systematic name describes the chemical structure of a chemical substance, thus giving some information about its chemical properties.. The Compendium of Chemical Terminology published by the IUPAC defines systematic name as "a name composed wholly of specially coined or selected syllables, with or without numerical prefixes; e.g. pentane, oxazole."
The prefix "spiro" followed by a Von-Baeyer descriptor describes in the nomenclature of organic compounds ring systems linked by only one common atom, the spiro atom. If several spiro atoms are present in the molecule, the prefix "spiro" is provided with a prefix ("dispiro", "trispiro", etc.) corresponding to the number of spiro atoms.
