Definition of alkyne in English: alkynenoun ˈalkʌɪnˈalkīn Chemistry Any of the series of unsaturated hydrocarbons containing a triple bond, including acetylene. Alkynes have the general formula: CnH₂n₋₂ Example sentencesExamples - Alkanes (sometimes called paraffins) have only single bonds, while alkenes (sometimes called olefins) have a carbon-carbon double bond, and alkynes have a carbon-carbon triple bond.
- By careful use of appropriate conditions and catalysts alkanes can be converted into other hydrocarbons such as the alkenes and alkynes.
- The first step is the addition of the proton to the pi bond of the alkene or alkyne, acting as the electron source.
- Originally the alkynes were called the acetylenes.
- The alkyne functional group is the carbon-carbon triple bond.
