The reaction of toluene with in the presence of 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
