Question

The reaction of toluene with Cl₂ in presence of FeCl₃ gives ‘X’ while the of toluene with Cl₂ in presence of light gives ‘Y’. Thus ‘X’ and ‘Y’are ______.

Options

• X = benzyl chloride
  Y = o and p – chlorotoluene

• X = m – chlorotoluene
  Y = p – chlorotoluene

• X = o and p–chlorotoluene
  Y = trichloromethylbenzene

• X = benzyl chloride,
  Y = m-chlorotoluene

Answer 1

The reaction of toluene with Cl₂ in presence of FeCl₃ gives ‘X’ while the of toluene with Cl₂ in presence of light gives ‘Y’. Thus ‘X’ and ‘Y’are X = o and p–chlorotoluene, Y = trichloromethylbenzene.

Explanation:

Toluene with Cl₂ in the presence of FeCl₃ generates 'X' owing to electrophilic substitution reactions at ortho and para locations, and toluene with Cl₂ in the presence of light gives 'Y' due to free radical substitution reactions.

Thus ‘X’ and ‘Y’ are X = o and p–chlorotoluene Y = trichloromethylbenzene.
