MCQ
Amongst the following, the compound that can be most readily sulphonated is
  • A
    Benzene
  • B
    Nitrobenzene
  • Toluene
  • D
    Chlorobenzene

Answer

Correct option: C.
Toluene
c
Toulene can be most readily sulfonated because of the electron releasing group attached to it. Nucleophilicity increases resulting in a fast attack to $E ^{\oplus}$ (during sulphonation).
