  2. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    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 ...

  3. Alkyne - Wikipedia

    en.wikipedia.org/wiki/Alkyne

    In 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 CnH2n−2. Alkynes are traditionally known as acetylenes, although the name ...

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    IUPAC nomenclature of organic chemistry. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1][2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3]

  5. List of straight-chain alkanes - Wikipedia

    en.wikipedia.org/wiki/List_of_straight-chain_alkanes

    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.

  6. E–Z notation - Wikipedia

    en.wikipedia.org/wiki/E–Z_notation

    Alitretinoin. For organic molecules with multiple double bonds, it is sometimes necessary to indicate the alkene location for each E or Z symbol. For example, the chemical name of alitretinoin is (2E,4E,6Z,8E)-3,7-dimethyl-9-(2,6,6-trimethyl-1-cyclohexenyl)nona-2,4,6,8-tetraenoic acid, indicating that the alkenes starting at positions 2, 4, and 8 are E while the one starting at position 6 is Z.

  7. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    Olefin metathesis. In organic chemistry, olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. [1][2] Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than ...

  8. Cis–trans isomerism - Wikipedia

    en.wikipedia.org/wiki/Cis–trans_isomerism

    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.

  9. Terminal alkene - Wikipedia

    en.wikipedia.org/wiki/Terminal_alkene

    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 ...
