पर्याय

• Electrophilic elimination reaction

• Electrophilic substitution reaction

• Free radical addition reaction

• Nucleophilic substitution reaction.

Answer 1

Toluene reacts with a halogen in the presence of iron (III) chloride giving ortho and para halo compounds. The reaction is electrophilic substitution reaction.

Explanation: 

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 AICI_3.
