Which of the following reactions are not given by Benzene?
Correct answer: A. Elimination
- A. Elimination
- B. Addition
- C. Substitution
- D. Hydrogenation
Explanation
Option A: There is no such evidence of elimination reaction in Benzene since it completely destroys the stability of Benzene.Addition reactions are given by Benzene. this option B is incorrect. Option C: Benzene can undergo substitution reactions such as alkylation, nitration, and sulfonation, and addition reactions including hydrogenation. A substitution reaction of benzene will involve the replacement of one or more hydrogen atoms with other functional groups.Option D:The hydrogenation of benzene, or the hydrogen addition reaction of benzene, involves the addition of 2, 4, or 6 hydrogens to the carbons of benzene. Cyclohexane is produced when benzene is completely hydrogenated. Cyclohexane is a useful solvent and a precursor in the production of other chemicals.

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.
