Benzene gives mainly_________?
Correct answer: B. Substitution reactions
- A. Addition reaction
- B. Substitution reactions
- C. Halogenation
- D. All of these
Explanation
Benzene mainly undergoes electrophilic substitution because substitution preserves its especially stable aromatic ring, whereas addition would destroy aromaticity. Halogenation is one type of substitution reaction, so option c is a narrower example and the likely trap; addition is not the main reaction.

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.
