|Chapter 10: Conjugation in Alkadienes and Allylic Systems|
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 π 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 π system does not have to be all C as in a C=C or C≡C but can also contain heteroatoms, e.g. C=O or C≡N.
