The second substitution in benzene ring would give rise isomeric products:
Correct answer: C. Three
- A. One
- B. Two
- C. Three
- D. Four
Explanation
When 1 more substituent is introduced.(I) will give 3 isomeric products, ortho, meta and para disubstituted benzenes.(II) will produce only 2 isomeric products.(III) will produce three isomeric products.(IV) will produce only one isomeric product.

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.
