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

Correct answer: X = o- and p-Chlorotoluene, Y = Trichloromethyl-benzene

Solution

In the presence of FeCl3, toluene undergoes electrophilic substitution to form o- and p-chlorotoluene (X). In the presence of light, a free radical substitution occurs at the methyl group, forming trichloromethyl-benzene (Y).
