Resonance Energy of Benzene
Benzene’s special stability is due to the delocalized π molecular orbital formation. The magnitude of this extra stability can be estimated by measuring the changes …
Molecular Orbital Structure of Benzene
Introduction The structure of benzene is best described in the modern molecular orbital theory. All six carbon atoms in benzene are sp2 hybridized. The sp2 …
Resonance Structure of Benzene
In the case of benzene, Kekule’s structures (1) and (2) represent the resonance structures. The actual structure of the molecule may be represented as a …
Kekule’ structure Of Benzene
Introduction: In 1865, Kekule suggested benzene consisted of a cyclic planar structure of six carbons with alternate double and single bonds. To each carbon was …
Evidence of Cyclic Structure of Benzene
