The reaction of toluene with Cl2 in the 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 = benzal chloride, Y = m-chlorotoluene
