alkyl group(ăl`kĭl), in chemistry, group of carbon and hydrogen atoms derived from an alkanealkane
, any of a group of aliphatic hydrocarbons whose molecules contain only single bonds (see chemical bond). Alkanes have the general chemical formula CnH2n+2.

The name of the alkyl group is derived from the name of its alkane by replacing the -ane suffix with -yl, e.g., methyl, CH3, from methane, CH4, and ethyl, C2H5, from ethane, C2H6. In some cases different alkyl groups can be formed from the same alkane by removing different hydrogen atoms; the alkyl groups are then distinguished by adding a prefix, e.g., 1-propyl or n-propyl, CH2CH2CH3, and 2-propyl or isopropyl, CH(CH3)2, both formed from propane, CH3CH2CH3.
