Acetylene \A*cet"y*lene\, n. (Chem.)
A gaseous compound of carbon and hydrogen, in the proportion
of two atoms of the former to two of the latter. It is a
colorless gas, with a peculiar, unpleasant odor, and is
produced for use as an illuminating gas in a number of ways,
but chiefly by the action of water on calcium carbide. Its
light is very brilliant.
--Watts.
Douglas Harper's Etymology Dictionary
gaseous hydrocarbon, 1864, from French acétylène, coined by French chemist Marcelin-Pierre-Eugène Berthelot (1823-1907) from chemical ending -ene + acetyl, which was coined from acetic in 1839 by German chemist Justus von Liebig; see acetic. Liebig's coinage was in reference to a different radical; acetyl was transferred to its current sense in 1850s, but Berthelot's coinage was based on the original use of acetyl.\n\nThe name acetylene is an unfortunate one as the hydrocarbon is not directly related to the modern acetyl radical and the molecule ... contains a triple bond, not a double bond which the suffix -ene (q.v.) implies.
[Flood, "Origins of Chemical Names," 1963]

Acetylene ( systematic name: ethyne) is the chemical compound with the formula CH. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.
As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°.
Acetylene is a 2005 album by The Walkabouts. It features themes of anger and chaos.
