Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016 [8]) exceeds that of any other organic compound. [ 9 ] [ 10 ] Much of this production goes toward creating polythene , which is a widely used plastic containing polymer chains of ethylene units in various chain lengths.
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]
It contains one triple bond and has two isomeric organic chemical compounds: 1-Butyne (ethylacetylene) 2-Butyne (dimethylacetylene) See also
1-Butyne is an organic compound with the formula CH 3 CH 2 C≡CH. It is a terminal alkyne. The compound is a common terminal alkyne substrate in diverse studies of catalysis. It is a colorless combustible gas. [1] 1-Butyne participates in reactions typical for terminal alkynes, such as alkyne metathesis, [2] hydrogenation, condensation with ...
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 alkynes.
Hydration is an important process in many other applications; one example is the production of Portland cement by the crosslinking of calcium oxides and silicates that is induced by water. Hydration is the process by which desiccants function. CuSO 4 ·5H 2 O is bright blue and has a rather different structure from its colourless anhydrous ...
In organic chemistry, alkynylation is an addition reaction in which a terminal alkyne (−C≡CH) is added to a carbonyl group (C=O) to form an α-alkynyl alcohol (R 2 C(−OH)−C≡C−R). [1] [2] When the acetylide is formed from acetylene (HC≡CH), the reaction gives an α-ethynyl alcohol. This process is often referred to as ethynylation.
