Which of the following reactions is not caused by benzene?
Correct answer: A. Elimination
- A. Elimination
- B. Addition
- C. Substitution
- D. Dehydration
Explanation
There is no such evidence of an elimination reaction in Benzene since it completely destroys its stability.Benzene generally also resists addition reactions because that would cause the loss of stability of benzene; however, there are still several reactions in which addition occurs. Example: addition of hydrogen and Nickel/Palladium catalysts to benzene, producing cyclohexane; preparation of benzene hexachloride from benzene by the reaction with Chlorine and sunlight, etc. So this option is also eliminated.

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.
