metüül
Metüül, or the methyl group, is the simplest alkyl substituent in organic chemistry. It consists of a single carbon atom bonded to three hydrogen atoms, giving the formula CH3–. When attached to a larger carbon skeleton, it acts as a substituent and is common in alkanes, alcohols, aromatics and many biomolecules. In shorthand, chemists write Me– to denote the methyl group.
The term metüül is Estonian for the methyl substituent; in IUPAC nomenclature the substituent is methyl, and
Methyl groups participate in many reactions. Benzylic and allylic C–H bonds adjacent to aromatic or vinyl groups
Methyl groups are widespread in organic molecules, including methanol, methane-derived compounds, amino acids, nucleotides, and lipids.
Methyl-containing compounds range from relatively benign solvents to toxic reagents; many methylating agents are hazardous and
