alkyyliä
Alkyyliä refers to a univalent organic radical derived from an alkane by removal of a single hydrogen atom. These groups are typically represented by the general formula R, where R signifies any alkyl group. Alkyl groups are saturated hydrocarbon substituents. For example, if methane (CH4) loses a hydrogen atom, it forms a methyl group (CH3-). If ethane (C2H6) loses a hydrogen atom, it forms an ethyl group (C2H5-). The naming of alkyl groups follows the convention of replacing the "-ane" suffix of the parent alkane with "-yl".
Common examples of alkyl groups include methyl (CH3-), ethyl (C2H5-), propyl (C3H7-), and butyl (C4H9-). These groups
