  2. Homologous series - Wikipedia

    en.wikipedia.org/wiki/Homologous_series

    The name "homologous series" is also often used for any collection of compounds that have similar structures or include the same functional group, such as the general alkanes (straight and branched), the alkenes (olefins), the carbohydrates, etc. However, if the members cannot be arranged in a linear order by a single parameter, the collection ...

  3. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    More complex alkenes may be named with the E–Z notation for molecules with three or four different substituents (side groups). For example, of the isomers of butene , the two methyl groups of ( Z )-but-2 -ene (a.k.a. cis -2-butene) appear on the same side of the double bond, and in ( E )-but-2-ene (a.k.a. trans -2-butene) the methyl groups ...

  4. Homologation reaction - Wikipedia

    en.wikipedia.org/wiki/Homologation_reaction

    A homologous series is a group of compounds that differ by a constant unit, generally a methylene (−CH 2 −) group. The reactants undergo a homologation when the number of a repeated structural unit in the molecules is increased. The most common homologation reactions increase the number of methylene (−CH 2 −) units in saturated chain ...

  5. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    Alkyl groups form homologous series. The simplest series have the general formula −C n H 2n+1. Alkyls include methyl, (−CH 3), ethyl (−C 2 H 5), propyl (−C 3 H 7), butyl (−C 4 H 9), pentyl (−C 5 H 11), and so on. Alkyl groups that contain one ring have the formula −C n H 2n−1, e.g. cyclopropyl and cyclohexyl.

  6. Hydrosilanes - Wikipedia

    en.wikipedia.org/wiki/Hydrosilanes

    Akin to the hydrosilylation of alkenes, hydrosilanes add to a variety of unsaturated substrates. In one example, PMHS. In one study triethylsilane is used in the conversion of a phenyl azide to an aniline: [7] In this reaction ACCN is a radical initiator and an aliphatic thiol transfers radical character to the silylhydride.

  7. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    With their repeated – CH 2 units, the alkanes constitute a homologous series of organic compounds in which the members differ in molecular mass by multiples of 14.03 u (the total mass of each such methylene-bridge unit, which comprises a single carbon atom of mass 12.01 u and two hydrogen atoms of mass ~1.01 u each).

  8. 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.

  9. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    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.
