August Kekulé's structure of benzene failed to explain _.
Correct answer: D. All of these options are correct
- A. Benzene reactivity
- B. That benzene has dual character
- C. That benzene has less heat of formation
- D. All of these options are correct
Explanation
Kekule's structure does not explain the extra ordinary stable nature of benzene molecule and its lack of reactivity towards addition reactions, resistance towards oxidation etc. According to Kekule's structure benzene contains three double bonds and hence the chemical properties of benzene should resemble those of alkene, but in actuality, it is not so as Benzene is highly stable and forms substitution compounds easily.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
