In chemistry, a methyl group is a hydrophobic alkyl functional group named after methane (4). It has the formula -3 and is often abbreviated -Me. Such hydrocarbon groups occur in many organic compounds. Methyl groups can be incorporated into organic compounds by an SN2 reaction on iodomethane, or by the reaction of methyl lithium or MeMgCl with a carbon atom that's substituted with a leaving group. Reactivity The introduction of methyl groups as substituents into a compound usually increases it… (More on Methyl)
