A 3D model of ethyne (acetylene), the simplest alkyne. In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbonâcarbon triple bond. The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula CnH2nâ2.
The general formula of an alkene is CnH2n. An alkyne is a hydrocarbon containing triple bonds. The general formula of an alkyne is CnH2n-2. The term saturated is used to refer to a compound in which all carbon-carbon bonds are single bonds and every carbon atom is connected to a different atom.
