The reaction of toluene with chlorine in the presence of iron and in the absence of light yields:

This is a multiple choice answer as classified in NCERT Exemplar

The Correct Answer is Option (iv).

By electrophilic substitution, aromatic arenes react with chlorine in the presence of Lewis acid catalysts such as iron (III) chloride, yielding ortho and para isomers of haloarenes. (ii) and (iii) are both products of the reaction. Cl₂ forms a coordination complex with FeCl₃, creating the Cl + FeCl₄ - complex, which has a small positive charge on Cl and a negative charge on FeCl₄ - . This Cl⁺  then interacts with the aromatic double bonds of the toluene molecule to create an addition product, which is su

This Cl⁺  then interacts with the aromatic double bonds of the toluene molecule to create an addition product, which is subsequently deprotonated to form a mixture of o-, p-, and m- chlorotoluene isomers. Because the m- isomer is highly unstable, the product is not accessible in the o- and p- forms.
