  2. Alkyne - Wikipedia

    en.wikipedia.org/wiki/Alkyne

    A 3D model of ethyne , the simplest 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 C n H 2n−2.

  3. Acetylene - Wikipedia

    en.wikipedia.org/wiki/Acetylene

    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]

  4. List of reagents - Wikipedia

    en.wikipedia.org/wiki/List_of_reagents

    General Description Acetic acid: an organic acid; is one of the simplest carboxylic acids: Acetone: an organic compound; simplest example of the ketones: Acetylene: a hydrocarbon and the simplest alkyne; widely used as a fuel and chemical building block Ammonia: inorganic; the precursor to most nitrogen-containing compounds; used to make fertilizer

  5. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    An acyclic alkyl has the general formula of −C n H 2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group.

  6. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    Acyclic alkenes, with only one double bond and no other functional groups (also known as mono-enes) form a homologous series of hydrocarbons with the general formula C n H 2n with n being a >1 natural number (which is two hydrogens less than the corresponding alkane).

  7. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions.The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.

  8. 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 ...

  9. Polyyne - Wikipedia

    en.wikipedia.org/wiki/Polyyne

    Using various techniques, polyynes H(−C≡C−) n H with n up to 4 or 5 were synthesized during the 1950s. [12] Around 1971, T. R. Johnson and D. R. M. Walton developed the use of end-caps of the form – SiR 3, where R was usually an ethyl group, to protect the polyyne chain during the chain-doubling reaction using Hay's catalyst (a copper(I)–TMEDA complex).
