  2. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    [15] [16] The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol" (which since 1892 is called "methanol"). Methyl is the IUPAC nomenclature of organic chemistry term for an alkane (or alkyl) molecule, using the prefix "meth-" to indicate the presence of a single carbon.

  3. Methanol - Wikipedia

    en.wikipedia.org/wiki/Methanol

    The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol". This was shortened to "methanol" in 1892 by the International Conference on Chemical Nomenclature. [29] The suffix-yl, which, in organic chemistry, forms names of carbon groups, is from the word methyl.

  4. Methylation - Wikipedia

    en.wikipedia.org/wiki/Methylation

    Methylation, in the chemical sciences, is the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group. Methylation is a form of alkylation, with a methyl group replacing a hydrogen atom. These terms are commonly used in chemistry, biochemistry, soil science, and biology.

  5. Methylene group - Wikipedia

    en.wikipedia.org/wiki/Methylene_group

    The hexamethylene diamine molecule contains six methylene groups. A methylene group is any part of a molecule that consists of two hydrogen atoms bound to a carbon atom, which is connected to the remainder of the molecule by two single bonds. [1]

  6. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    The methyl "substituent" or "group" is highlighted red. According to the usual rules of nomenclature, alkyl groups are included in the name of the molecule before the root, as in methylpentane . This name is, however, ambiguous, as the methyl branch could be on various carbon atoms.

  7. Methylcobalamin - Wikipedia

    en.wikipedia.org/wiki/Methylcobalamin

    It differs from cyanocobalamin in that the cyano group at the cobalt is replaced with a methyl group. [1] Methylcobalamin features an octahedral cobalt(III) centre and can be obtained as bright red crystals. [2] From the perspective of coordination chemistry, methylcobalamin is notable as a rare example of a compound that contains metal–alkyl ...

  8. Methyl radical - Wikipedia

    en.wikipedia.org/wiki/Methyl_radical

    Methyl radical is an organic compound with the chemical formula CH • 3 (also written as [CH 3] •). It is a metastable colourless gas, which is mainly produced in situ as a precursor to other hydrocarbons in the petroleum cracking industry. It can act as either a strong oxidant or a strong reductant, and is quite corrosive to metals.

  9. Methylaluminoxane - Wikipedia

    en.wikipedia.org/wiki/Methylaluminoxane

    MAO serves multiple functions in the activation process. First it alkylates the metal-chloride pre-catalyst species giving Ti/Zr-methyl intermediates. Second, it abstracts a ligand from the methylated precatalysts, forming an electrophilic, coordinatively unsaturated catalysts that can undergo ethylene insertion.
