Toluene reacts with halogen in presence of iron(III) chloride giving ortho and para halo compounds, the reaction is electrophilic substitution reaction.
The H atom or aromatic nucleus is replaced with Cl atom. The electrophile in this reaction is Cl+ ion obtained by the reaction of Cl2 with AlCl3.

Reaction of Toluene with Halogen in presence of Iron(III) Chloride
The reaction of toluene with halogen in the presence of iron(III) chloride is an example of electrophilic substitution reaction.
Electrophilic Substitution Reaction
- Electrophilic substitution is a type of reaction in which an electrophile (an electron-deficient species) replaces a functional group or an atom in a molecule.
- In this type of reaction, an electrophile attacks a nucleophilic site in the reactant molecule, leading to the substitution of an atom or a group.
- Electrophilic substitution reactions are commonly observed in aromatic compounds, where the aromatic ring acts as a nucleophile.
Reaction of Toluene with Halogen
- Toluene is an aromatic compound with a benzene ring substituted with a methyl group (-CH3).
- When toluene reacts with a halogen (such as chlorine or bromine), the halogen replaces one of the hydrogen atoms in the aromatic ring.
- The reaction requires the presence of a catalyst, such as iron(III) chloride (FeCl3), which helps in the formation of the electrophile.
Formation of Electrophile
- In the presence of iron(III) chloride, the halogen molecule (X2) undergoes homolytic cleavage to form two halogen radicals (X·).
- The iron(III) chloride then interacts with one of the halogen radicals, abstracting an electron and forming an iron halide complex (FeX4·).
- This complex acts as an electrophile in the reaction.
Attack of Electrophile on Toluene
- The electrophile (FeX4·) generated in the previous step attacks the aromatic ring of toluene.
- The attack occurs at the ortho and para positions of the ring, leading to the formation of ortho-halotoluene and para-halotoluene.
- The attack involves the formation of a sigma complex, followed by the elimination of the iron halide complex and regeneration of the aromatic system.
Overall Reaction
The overall reaction can be represented as follows:
Toluene + Halogen + Iron(III) chloride → Ortho-halotoluene + Para-halotoluene + Iron halide complex
