Functional group

A group of atoms in a molecule that gives it characteristic chemical reactions.

An atom or group of atoms responsible for the characteristic reactions of an organic compound.

A group of atoms within a molecule that determines its characteristic chemical reactions.

An atom or group of atoms that determines a compound's characteristic chemical reactions.
