Butyne is an alkyne that contains 4 carbon and 6 hydrogen. It contains one triple bond and has two isomeric organic chemical compounds: 1-Butyne (ethylacetylene)
The C≡C bond distance of 118 picometers (for C 2 H 2) is much shorter than the C=C distance in alkenes (132 pm, for C 2 H 4) or the C–C bond in alkanes (153 pm).

[2] 2-Methylbut-3-yn-2-ol is produced on an industrial scale as a precursor to terpenes and terpenoids. 2-Methylbut-3-yn-2-ol is an intermediate in this industrial route to geraniol. [3] 2-Methylbut-3-yn-2-ol also is used as a monoprotected version of acetylene. For example, after arylation at carbon, the acetone can be removed with base: [4]

2-Butyne is of interest to physical chemists because of its very low torsional barrier and the problem of determining that barrier using high-resolution infrared spectroscopy. Analysis of its spectrum [3] leads to a determination that the torsional barrier is only 6 cm −1 (1.2 × 10 −22 J or 72 J mol −1).
