Since functional groups often act an "independent units" it is convenient to classify their chemical reactions in such a manner.  However, the presence of a adjacent p system in the form of a double (or triple) bond can alter the characteristic chemistry of the functional group, principally due to the effects of resonance within a conjugated system. This p system does not have to be all C as in a C=C or CºC but can also contain heteroatoms, e.g. C=O or CºN.
