What are Kekule structures?
Correct answer: C. The two-resonance structure of benzene
- A. The two isomers of benzene
- B. The isomers of arenes
- C. The two-resonance structure of benzene
- D. The two-resonance structure of phenols
Explanation
This option is correct because kekule structure represents the resonating structure of benzene according to which benzene has a ring structure which consists of cyclic planar structure of six carbon having alternate double and single bonds.

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.
