Ethyne is an organic compound with the chemical formula C₂H₂. It belongs to the alkyne family of hydrocarbons, which are characterized by the presence of a carbon-carbon triple bond. The structure of ethyne is H-C≡C-H. Each carbon atom is bonded to one hydrogen atom via a single covalent bond and to the other carbon atom via a triple covalent bond. Alkanes have single bonds (C-C), alkenes have double bonds (C=C), and alkynes have triple bonds (C≡C) between carbon atoms.
Hydrocarbons are classified based on the types of bonds between carbon atoms. Alkanes have only single bonds, alkenes have at least one double bond, and alkynes have at least one triple bond. Ethyne is the simplest alkyne.
