In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon –carbon double bond. [ 1 ] The double bond may be internal or in the terminal position. Terminal alkenes are also known as α-olefins. The International Union of Pure and Applied Chemistry (IUPAC) recommends using the name "alkene" only for acyclic hydrocarbons ...
Terminal alkynes, like acetylene itself, are mildly acidic, with pK a values of around 25. They are far more acidic than alkenes and alkanes, which have pK a values of around 40 and 50, respectively. The acidic hydrogen on terminal alkynes can be replaced by a variety of groups resulting in halo-, silyl-, and alkoxoalkynes.
Alkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula CnH2n+2.
Aliphatic compound. In organic chemistry, hydrocarbons (compounds composed solely of carbon and hydrogen) are divided into two classes: aromatic compounds and aliphatic compounds (/ ˌælɪˈfætɪk /; G. aleiphar, fat, oil). Aliphatic compounds can be saturated (in which all the C-C bonds are single requiring the structure to be completed, or ...
Hydrocarbon. Ball-and-stick model of the methane molecule, CH 4. Methane is part of a homologous series known as the alkanes, which contain single bonds only. In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [1]: 620 Hydrocarbons are examples of group 14 hydrides.
List of straight-chain alkanes. The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [1][2] Number of C atoms. Number of isomers [3][4] Number of isomers including stereoisomers [3][5] Molecular Formula. Name of straight chain.
As with organic compounds, the cis isomer is generally the more reactive of the two, being the only isomer that can reduce alkenes and alkynes to alkanes, but for a different reason: the trans isomer cannot line its hydrogens up suitably to reduce the alkene, but the cis isomer, being shaped differently, can.
The double bond of an alpha olefin is between the #1 and #2 (IUPAC) or α and β (common) carbon atoms. In organic chemistry, terminal alkenes (alpha-olefins, α-olefins, or 1-alkenes) are a family of organic compounds which are alkenes (also known as olefins) with a chemical formula CxH2x, distinguished by having a double bond at the primary ...
