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
X = Benzyl chloride, Y = m-chlorotoluene
X = Benzal chloride, Y = o-chlorotoluene
X = m-chlorotoluene, Y = p-chlorotoluene
X = o-and p-chlorotoluene, Y = Trichloromethyl benzene
