Sažetak

The stabilization energy of benzene (SE) is proposed to be ·
calculated from the increments of heats of formation in the homologous
series of conjugated polyenes. In this way 19.7 and 23.0
kcal/mol* are derived for $E, when benzene is compared to trans
and cis type polyenes, respectively. A comparison of the estimated
C-C bond energy of benzene to that of olefins leads to the conclusion
that C-C bonds are responsible for only about 2/3 of SE. It is
suggested that the rest of SE is connected with the difference in
strength of the aromatic and olefinic C-H bonds.
