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.
Cycloalkynes have a general formula C n H 2n−4. Because of the linear nature of the C−C≡C−C alkyne unit, cycloalkynes can be highly strained and can only exist when the number of carbon atoms in the ring is great enough to provide the flexibility necessary to accommodate this geometry.
In 1 H NMR spectroscopy, the hydrogen bonded to the carbon adjacent to double bonds will give a δ H of 4.5–6.5 ppm. The double bond will also deshield the hydrogen attached to the carbons adjacent to sp 2 carbons, and this generates δ H =1.6–2. ppm peaks. [14] Cis/trans isomers are distinguishable due to different J-coupling effect.

For those with 4 or more carbons, the linear forms can have straight-chain or branched-chain isomers. The lowercase prefix n-denotes the straight-chain isomer; for example, n-butane is straight-chain butane, whereas i-butane is isobutane. Cycloalkanes are isomers of alkenes, not of alkanes, because the ring's closure involves a C-C bond.
Four-carbon molecules are based on a skeleton made from four carbon atoms. They may be in a chain, branched chains, cycles or even bicyclic compounds C 4 H 4 isomers with CAS registry numbers. Hydrocarbons that include four atoms are: butane C 4 H 10; isobutane C 4 H 10; but-1-ene C 4 H 8; but-2-ene C 4 H 8; but-1-yne C 4 H 6; but-2-yne C 4 H 6 ...
