Alkyl（ alkyl ）, i.e. saturated hydrocarbon radical, is alkane One missing from the molecule hydrogen atom Resulting from Alkyl group , commonly referred to as R basis. Alkyl is a kind of chain like organic group containing only carbon and hydrogen atoms.

Compounds with different alkyl groups are a series of homologue 。 E.g. methyl CH three -， ethyl CH three CH two -Etc. methanol CH three OH、 Methyl chloride CH three Cl and other molecules contain methyl 。 ethanol CH three CH two OH、 Chloroethane CH three CH two Cl and other molecules contain ethyl.

Alkyl containing compounds exist everywhere in the environment, because alkyl is a natural and biosphere organic compound More common Constituent unit 。
