An overview of alkyls from a 1930s Soviet medical perspective, defining them as unfree monovalent hydrocarbon radicals used for organic nomenclature.

Encyclopedia entry (1928–1936)

ALKYLS, non-existent in the free state, are monovalent residues (radicals) of hydrocarbons. The name of alkyl is derived from the parent hydrocarbon by replacing the ending "ane" with "yl", for example, methyl -CH3, ethyl -C2H5, propyl -C3H7, etc. Similar residues of aromatic hydrocarbons are called "aryls": phenyl -C6H5, toluyl -C7H7, etc. These terms are used for the convenience of organic compound nomenclature.
