  2. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    Different ways of representing a methyl group (highlighted in blue) 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.

  3. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a ...

  4. Category:Methyl compounds - Wikipedia

    en.wikipedia.org/wiki/Category:Methyl_compounds

    Methyl compounds are chemical compounds formally derived from methane by replacement of one hydrogen atom with other atoms or functional groups. Methyl compounds contain the methyl group, CH 3, and have the general formula CH 3 X, where X is any chemical element or group.

    The side chains are grouped like this: 12-butyl-4,8-diethyl. (But this is not necessarily the final grouping, as functional groups may be added in between to ensure all groups are listed alphabetically.) The secondary functional groups are: a hydroxy- at carbon 5, a chloro- at carbon 11, a methoxy- at carbon 15, and a bromo- at carbon 18.

  6. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    Here three identical alkyl groups attached to carbon atoms 2, 3, and 3. The numbers are included in the name to avoid ambiguity about the position of the groups, and "tri" indicates that there are three identical methyl groups. If one of the methyl groups attached to the third carbon atom were instead an ethyl group, then the name would be 3 ...

  7. Methylmercury - Wikipedia

    en.wikipedia.org/wiki/Methylmercury

    This functional group is composed of a methyl group bonded to an atom of mercury. Its chemical formula is CH 3 Hg + (sometimes written as MeHg +). The Methylmercury compound has an overall charge of +1, with Hg in the +2 oxidation state. Methylmercury exists as a substituent in many complexes of the type [MeHgL] + (L = Lewis base) and MeHgX (X ...

  8. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group (−CH 3) that is single-bonded to a carbonyl (C=O), making it an acyl group. The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R) of the molecule.

  9. Methoxy group - Wikipedia

    en.wikipedia.org/wiki/Methoxy_group

    In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula R−O−CH 3. On a benzene ring, the Hammett equation classifies a methoxy substituent at the para position as an electron-donating group, but as an electron-withdrawing group if at the meta position.
