Alkynes
\ce \ce Acetylene \ce \ce \ce Propyne \ce \ce \ce \ce 1-Butyne In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula . Alkynes are traditionally known as acetylenes, although the name ''acetylene'' also refers specifically to , known formally as ethyne using IUPAC nomenclature. Like other hydrocarbons, alkynes are generally hydrophobic. Structure and bonding In acetylene, the H–C≡C bond angles are 180°. By virtue of this bond angle, alkynes are rod-like. Correspondingly, cyclic alkynes are rare. Benzyne cannot be isolated. The C≡C bond distance of 121 picometers is much shorter than the C=C distance in alkenes (134 pm) or the C–C bond in alkanes (153 pm). : The triple bond is very strong with a bond strength of 839 kJ/mol. The sigma bond contributes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-Hexyne
2-Hexyne is an organic compound that belongs to the alkyne group. Just like its isomers, it also has the chemical formula of C6H10. Reactions 2-Hexyne can be semihydrogenated to yield 2-hexene or fully hydrogenated to hexane. With appropriate noble metal catalysts it can selectively form ''cis''-2-hexene. 2-Hexyne can act as a ligand on gold atoms. With strong sulfuric acid, the ketone 2-hexanone is produced. However this reaction also causes polymerization and charring. Under heat and pressure 2-hexyne polymerizes to linear oligomers and polymers. This can be hastened by some catalysts such as molybdenum pentachloride with tetraphenyl tin. However Ziegler–Natta catalyst A Ziegler–Natta catalyst, named after Karl Ziegler and Giulio Natta, is a catalyst used in the synthesis of polymers of 1-alkenes (alpha-olefins). Two broad classes of Ziegler–Natta catalysts are employed, distinguished by their solubility: * He ...s have no action as the triple bond is hindered. Refere ...

1-Hexyne
1-Hexyne (''n''-butylacetylene) is a hydrocarbon consisting of a straight six-carbon chain having a terminal alkyne. Its molecular formula is C6H10. It is a liquid at room temperature that is colorless or pale yellow in appearance. Reactions 1-Hexyne also reacts with diethyl fumarate to produce . Uses 1-Hexyne is used for the production of complex molecules in the agrochemical, pharmaceutical, and perfumery industries. It is a component in cycloaddition reactions that produce substituted azide In chemistry, azide is a linear, polyatomic anion with the formula and structure . It is the conjugate base of hydrazoic acid . Organic azides are organic compounds with the formula , containing the azide functional group. The dominant applic ...s and isoindolinones.
