Chapter 10: Conjugation in Alkadienes and Allylic Systems |
 |
Summary
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.
