The oxidation of a methyl group occurs widely in nature and industry. The oxidation products derived from methyl are hydroxymethyl group −CH 2 OH, formyl group −CHO, and carboxyl group −COOH. For example, permanganate often converts a methyl group to a carboxyl (−COOH) group, e.g. the conversion of toluene to benzoic acid.
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.
The structures of many reagents are often misunderstood because simplified formulas are presented in reaction schemes whereas the actual structures are more complex. Examples are methyl lithium and lithium diisopropylamide. Readers of Wikipedia often comment (complain) that structures shown are incorrect for this reason.
Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals , including formaldehyde , acetic acid , methyl tert -butyl ether , methyl benzoate , anisole , peroxyacids , as well as a host of more specialized chemicals.
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.
Molecular structure of caffeine. Methyl groups are implied, but not visualized.. In chemical graph theory and in mathematical chemistry, a molecular graph or chemical graph is a representation of the structural formula of a chemical compound in terms of graph theory.
The group may be represented as −CH 2 − or >CH 2, where the '>' denotes the two bonds. This stands in contrast to a situation where the carbon atom is bound to the rest of the molecule by a double bond, which is preferably called a methylidene group, represented =CH 2. [2] Formerly the methylene name was used for both isomers.
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.
