Alkyl groups are a class of organic chemical substituents derived from alkanes. An alkyl group is formed by removing a single hydrogen atom from an alkane molecule. For example, if you remove a hydrogen atom from methane (CH4), you get a methyl group (CH3-). If you remove a hydrogen from ethane (C2H6), you get an ethyl group (C2H5-). The general formula for a saturated alkyl group is CnH2n+1. The name of the alkyl group is typically derived from the name of the parent alkane by replacing the "-ane" ending with "-yl". Thus, methane becomes methyl, ethane becomes ethyl, propane becomes propyl, and so on.

Alkyl groups are important building blocks in organic chemistry. They are often attached to other functional groups or molecules, influencing their chemical and physical properties. For instance, the length and branching of an alkyl chain can affect a molecule's solubility, boiling point, and reactivity. Alkyl groups are considered saturated hydrocarbon radicals because they contain only single bonds between carbon atoms and hydrogen atoms and have a single point of attachment to another atom or group. They are also nonpolar due to the similar electronegativity of carbon and hydrogen.
