Correct answer: B. Hexagonal planar
- A. Tetrahedral
- B. Hexagonal planar
- C. Hexagonal irregular
- D. Trigonal planar

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.
