Benzene \Ben"zene\, n. [From Benzoin.] (Chem.) A volatile, very inflammable liquid, C6H6, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum.
Benzene nucleus, Benzene ring (Chem.), a closed chain or ring, consisting of six carbon atoms, each with one hydrogen atom attached, regarded as the type from which the aromatic compounds are derived. This ring formula is provisionally accepted as representing the probable constitution of the benzene molecule, C6H6, and as the type on which its derivatives are formed.
Douglas Harper's Etymology Dictionary
1835, benzine, altered from German Benzin, coined in 1833 by German chemist Eilhardt Mitscherlich (1794-1863) from Benz(oesäure) "benzoic acid" + -in, indicating "derived from" (see -ine (2)). Mitscherlich obtained it from a distillation of benzoic acid, obtained from benzoin. The form benzene (with hydrocarbon suffix -ene), proposed in 1835, began to be used from 1838 in English, but in mid-19c. it also commonly was called benzol.
n. (context organic compound English) An aromatic hydrocarbon of formula C6H6 whose structure consists of a ring of alternate single and double bonds.

Benzene is an aromatic hydrocarbon.
Benzene or related words may also refer to:
Benzene is an important organic chemical compound with the chemical formula C H. The benzene molecule is composed of 6 carbon atoms joined in a ring with 1 hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.
Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals. Because of the cyclic continuous pi bond between the carbon atoms, benzene is classed as an aromatic hydrocarbon, the second [n]- annulene (-annulene). It is sometimes abbreviated Ph–H. Benzene is a colorless and highly flammable liquid with a sweet smell. It is used primarily as a precursor to the manufacture of chemicals with more complex structure, such as ethylbenzene and cumene, of which billions of kilograms are produced. Because benzene has a high octane number, it is an important component of gasoline.
Because benzene is a human carcinogen, most non-industrial applications have been limited.
