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 attached one hydrogen. Benzene, according to this proposal, was simple 1,3,5-cyclohexatriene. Kekule’s structure of benzene explained satisfactorily the following points. 1. That benzene contains three double bonds. 2. All six […]

Evidence of Cyclic Structure of Benzene

Introduction: The cyclic structure of benzene, with alternating single and double bonds, has been a subject of considerable scientific interest. Several lines of evidence support the cyclic, rather than the classical Kekulé structures with fixed single and double bonds, for the benzene molecule. Here are some key pieces of evidence: (1) Substitution of Benzene: Benzene […]
