The monohalomethanes are organic compounds in which a hydrogen atom in methane is replaced by a halogen. They belong to the haloalkanes or to the subgroup of halomethanes.
The four common members are fluoromethane, chloromethane, bromomethane and iodomethane.
Historical name for this group is methyl halides; it's still widely used. The compounds of this class are often described as or MeX.
