A 3D model of ethyne (), the simplest alkyneIn 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.
Propyne (methylacetylene) is an alkyne with the chemical formula CH 3 C≡CH. It is a component of MAPD gas —along with its isomer propadiene (allene), which was commonly used in gas welding . Unlike acetylene , propyne can be safely condensed .

2-Butyne (dimethylacetylene, crotonylene or but-2-yne) is an alkyne with chemical formula CH 3 C≡CCH 3.Produced artificially, it is a colorless, volatile, pungent liquid at standard temperature and pressure.
The hexynes are a subgroup from the group of alkynes. It consists of several isomeric compounds having the formula C 6 H 10. The linear and branched members are: 1-Hexyne (n-butylacetylene) 2-Hexyne (methylpropylacetylene) 3-Hexyne (diethylacetylene) 3-methylpent-1-yne; 4-methylpent-1-yne; 4-methylpent-2-yne; 3,3-dimethylbut-1-yne
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.
1-Butyne is an organic compound with the formula CH 3 CH 2 C≡CH. It is a terminal alkyne. The compound is a common terminal alkyne substrate in diverse studies of catalysis. It is a colorless combustible gas. [1] 1-Butyne participates in reactions typical for terminal alkynes, such as alkyne metathesis, [2] hydrogenation, condensation with ...
