The four common [a] 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 CH 3 X or MeX (X - any halogen, Me - methyl group ).

An example of photochlorination at low temperatures and under ambient pressure is the chlorination of chloromethane to dichloromethane. The liquefied chloromethane (boiling point -24 °C) is mixed with chlorine in the dark and then irradiated with a mercury-vapor lamp. The resulting dichloromethane has a boiling point of 41 °C and is later ...
