The reaction of toluene with Cl₂ in presence of FeCl₃ gives 'X' and reaction in presence of

light gives 'Y'. Thus, 'X' and 'Y' are

1. X = Benzal chloride, Y = o-chlorotoluene

2. X = m-chlorotoluene, Y= p-chlorotoluene

3. X = o-and p-chlorotoluene, Y=trichloromethyl benzene

4. X = Benzyl chloride, Y = m-chlorotoluene

In a set of reactions, ethyl benzene yielded a product D.

Aniline in a set of the following reactions yielded a coloured product 'Y'.

The structure of 'Y' would be
