DefinitionThis section has been translated automatically.
Alkynes (formerly acetylenes and acetylene hydrocarbons; international designation: alkyne) designate chemical compounds from the group of unsaturated aliphatic hydrocarbons. Alkyne have at least one carbon-carbon triple bond (R-C≡C-R) at any position.
General informationThis section has been translated automatically.
Alkyne with a single triple bond form a homologous series with the general molecular formula CnH2n-2 (with n = 2, 3, 4, ...). These include ethyne (C2H2); propyne (C3H4); 1-butyne (C4H6); 1-pentyne (C5H8); 1-hexylene (C6H10); 1-heptyne (C7H12); 1-octyne (C8H14); 1-nonyne (C9H16); 1-decyne (C10H18).
Compounds with 2 or >2 C-C triple bonds are called polyins.
