The chlorination of benzene, catalyzed by FeCl₃:
C₆H₅ + [tex]Cl_{2}[/tex] + FeCl₃→ C₆H₅Cl+HCl
The Lewis acid is [tex]Cl_{2}[/tex] and the Lewis base is C₆H₅.
What is chlorination?
- Any procedure or reaction in which a molecule is exposed to chlorine (and no other elements). An alkene is chlorinated by electrophilic addition of chlorine .
- Benzene ring chlorination by electrophilic aromatic substitution.
- Since the oxy-chlorination and direct chlorination processes are exothermic, effective temperature controllers are needed to maintain the reactions's ideal conditions.
- A chain reaction is the mechanism. In a chain reaction, a new reactive species is produced at the end for each reactive species that was present at the beginning, which keeps the reaction going.
- Free radical chain reaction or free radical substitution is the name of the overall process.
