Reduction of benzene is presence of Ni gives:
Correct answer: A. Cyclohexane
- A. Cyclohexane
- B. Heterocyclic
- C. Alicyclic
- D. Unsaturated aliphatic
Explanation
Reduction of benzene in the presence of nickel (Ni) results in the formation of cyclohexane. This reaction is known as catalytic hydrogenation, which involves the addition of hydrogen gas (H2) in the presence of a catalyst, usually a transition metal such as Ni, Pt, or Pd.

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.
