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
