Which one of the following is not a characteristic of benzene?
Correct answer: D. High reactivity
- A. Aromaticity
- B. Stability
- C. To follow Huckel rule
- D. High reactivity
Explanation
The delocalised ring of six pi electrons makes benzene unusually stable, so it resists addition and reacts only under forcing conditions, preferring substitution which preserves the aromatic system. Aromaticity, stability and obedience to Huckel's 4n plus 2 rule are all genuine features. Expecting benzene to behave like a reactive alkene is precisely the misconception this question targets.

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.
