  2. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    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. The smallest alkyl group is methyl, with the formula −CH 3 ...

  3. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...

  4. Methylidyne radical - Wikipedia

    en.wikipedia.org/wiki/Methylidyne_radical

    Methylidyne, or (unsubstituted) carbyne, is an organic compound whose molecule consists of a single hydrogen atom bonded to a carbon atom. It is the parent compound of the carbynes, which can be seen as obtained from it by substitution of other functional groups for the hydrogen.

  5. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    An alkyl group is an alkane-based molecular fragment that bears one open valence for bonding. They are generally abbreviated with the symbol for any organyl group, R, although Alk is sometimes used to specifically symbolize an alkyl group (as opposed to an alkenyl group or aryl group).

  6. Methine group - Wikipedia

    en.wikipedia.org/wiki/Methine_group

    Methine or methylylidene (IUPAC) In organic chemistry, a methine group or methine bridge is a trivalent functional group =CH−, derived formally from methane.It consists of a carbon atom bound by two single bonds and one double bond, where one of the single bonds is to a hydrogen.

  7. Ether - Wikipedia

    en.wikipedia.org/wiki/Ether

    A typical example of the first group is the solvent and anaesthetic diethyl ether, commonly referred to simply as "ether" (CH 3 −CH 2 −O−CH 2 −CH 3). Ethers are common in organic chemistry and even more prevalent in biochemistry , as they are common linkages in carbohydrates and lignin .
