When toluene is treated with chlorine in the presence of FeCl3, the major products formed are

1. m-chlorobenzene
2. benzoyl chloride
3. benzyl chloride
4. o- and p-chlorotoluenes

Correct answer: o- and p-chlorotoluenes

Solution

The presence of FeCl3 as a catalyst facilitates the electrophilic aromatic substitution reaction, where chlorine substitutes hydrogen atoms on the aromatic ring of toluene. Due to the electron-donating methyl group, the substitution occurs predominantly at the ortho and para positions, leading to the formation of o- and p-chlorotoluenes.
