n.
An atom or group of atoms, such as a carboxyl group, in an organic compound that defines the structure of a family of compounds and determines the properties of the family.

functional group

n
(Chemistry) chem the group of atoms in a compound, such as the hydroxyl group in an alcohol, that determines the chemical behaviour of the compound

n.
a group of atoms responsible for the characteristic behavior of the class of compounds in which the group occurs, as the hydroxyl group in alcohols.
