A 3D model of ethyne , the simplest alkyne. In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. [1] The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula C n H 2n−2.
Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H. It is a hydrocarbon and the simplest alkyne. [8] 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. [9]
An acyclic alkyl has the general formula of −C n H 2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group.

1-Pentyne is an organic compound with the formula CH 3 CH 2 CH 2 C≡CH. It is a terminal alkyne , in fact the smallest that is liquid at room temperature. The compound is a common terminal alkyne substrate in diverse studies of catalysis.
2-Octyne, also known as methylpentylethyne and oct-2-yne, [1] is a type of alkyne with a triple bond at its second carbon (the '2-' indicates the location of the triple bond in the chain). Its formula is C 8 H 14. [2] Its density at 25 °C and otherwise stable conditions is 0.759 g/ml. [3] The boiling point is 137 °C. [3]
Alkynes with the formula H(−C≡C−) n H and n from 2 to 6 can be detected in the decomposition products of partially oxidized copper(I) acetylide ((Cu +) 2 (− C≡C −) (an acetylene derivative known since 1856 or earlier) by hydrochloric acid. A "carbonaceous" residue left by the decomposition also has the spectral signature of (−C≡ ...
Butyne is an alkyne that contains 4 carbon and 6 hydrogen. It contains one triple bond and has two isomeric organic chemical compounds: It contains one triple bond and has two isomeric organic chemical compounds:
