MDCAT Chemistry QUESTION #4343
Question 1
Chlorination of benzene in the presence of iron(III) chloride involves mechanism of:
  • Electrophilic addition
  • Electrophilic Substitution✔️
  • Free radical Substitution
  • Free radical halogenation
Correct Answer Explanation
Benzene undergoes electrophilic aromatic substitution (EAS). $FeCl_3$ acts as a Lewis acid catalyst, generating the electrophile $Cl^+$ from $Cl_2$, which then attacks the benzene ring.
