A 3D model of ethyne (), the simplest alkyneIn organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. [1] The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula C n H 2n−2.
Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H. It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. [9]
By hydration of alkynes. [10] Such processes occur via enols and require the presence of an acid and mercury(II) sulfate (HgSO 4). Subsequent enol–keto tautomerization gives a ketone. This reaction always produces a ketone, even with a terminal alkyne, the only exception being the hydration of acetylene, which produces acetaldehyde.

General formula for a ketene. In organic chemistry, a ketene is an organic compound of the form RR'C=C=O, where R and R' are two arbitrary monovalent chemical groups (or two separate substitution sites in the same molecule). [1] The name may also refer to the specific compound ethenone H 2 C=C=O, the simplest ketene. [2]
1-Decyne is the organic compound with the formula C 8 H 17 C≡CH. It is a terminal alkyne. A colorless liquid, 1-decyne is used as a model substrate when evaluating methodology in organic synthesis. It participates in a number of classical reactions including Suzuki-Miyaura couplings, Sonogashira couplings, [1] Huisgen cycloadditions, [2] and ...
