RESONANCE
• Resonance energy is defined as the difference in energy between Kekulé benzene
(cyclohexatriene)
& benzene itself.
(cyclohexatriene)
& benzene itself.
Theoretical
3 x -28.6 = -85.8
3 x -28.6 = -85.8
Experimental
value = -49.8

• An estimate
for C6H6 can
be carried out
by comparing
the redn. rxn
of C6H10 with
that of benzene.
