The most readily sulphonated compound is:
Correct answer: D. Toluene
- A. Benzene
- B. Chlorobenzene
- C. Nitrobenzene
- D. Toluene
Explanation
The sulphonation reaction of aromatic compounds involves the electrophilic substitution of a hydrogen atom on the aromatic ring with a sulfonic acid group (-SO₃H). Toluene, with its electron-donating methyl group, has increased electron density on the benzene ring, making it more reactive towards electrophilic substitution reactions like sulphonation. Benzene, chlorobenzene, and nitrobenzene are less reactive due to their neutral or electron-withdrawing substituents, which decrease electron density on the benzene ring.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
