  2. Acetylene - Wikipedia

    en.wikipedia.org/wiki/Acetylene

    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]

    en.wikipedia.org/wiki/Ethylene

    Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

  4. Vinyl group - Wikipedia

    en.wikipedia.org/wiki/Vinyl_group

    Chemical structure of the vinyl functional group. In organic chemistry , a vinyl group (abbr. Vi ; [ 1 ] IUPAC name : ethenyl group [ 2 ] ) is a functional group with the formula −CH=CH 2 . It is the ethylene (IUPAC name: ethene) molecule ( H 2 C=CH 2 ) with one fewer hydrogen atom.

  5. Alkyne - Wikipedia

    en.wikipedia.org/wiki/Alkyne

    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.

  6. Ethyltoluene - Wikipedia

    en.wikipedia.org/wiki/Ethyltoluene

    Ethyltolune describes organic compounds with the formula CH 3 C 6 H 4 CH 2 CH 3.Three isomers exist: 1,2- 1,3-, and 1,4-. All are colorless liquids, immiscible in water, with similar boiling points.

  7. Acetylide - Wikipedia

    en.wikipedia.org/wiki/Acetylide

    In chemistry, an acetylide is a compound that can be viewed as the result of replacing one or both hydrogen atoms of acetylene (ethyne) HC≡CH by metallic or other cations. Calcium carbide is an important industrial compound, which has long been used to produce acetylene for welding and illumination. It is also a major precursor to vinyl ...

  8. 2-Butyne - Wikipedia

    en.wikipedia.org/wiki/2-butyne

    Symmetry analysis using the Molecular Symmetry Group [4] [5] G 36 shows that one would need to analyse its high resolution rotation-vibration Raman spectrum to determine its equilibrium structure. 2-Butyne ( dimethylethyne ) forms with 5-decyne ( dibutylethyne ), 4-octyne ( dipropylethyne ) and 3-hexyne ( diethylethyne ) a group of symmetric ...

  9. Polyacetylene - Wikipedia

    en.wikipedia.org/wiki/Polyacetylene

    The structure of polyacetylene films have been examined by both infrared spectroscopy [21] and Raman spectroscopy, [22] and found that the structure depends on synthetic conditions. When the synthesis is performed below −78 °C, the cis form predominates, while above 150 °C the trans form is favored.
