When toluene is treated with Cl2 in the presence of Fe in dark, the product formed is
Answer: B
The product is a mixture of o- and p-chlorotoluene.
With a Lewis acid catalyst (Fe, which forms FeCl3) and in the dark, chlorine substitutes on the ring by electrophilic aromatic substitution. The methyl group is ortho-para directing, so 2-chlorotoluene and 4-chlorotoluene are formed.
Benzyl chloride and benzal dichloride are side-chain products, formed by free radical chlorination in sunlight or on heating without a catalyst. Di- and trichlorotoluenes need excess chlorine, not the simple monochlorination asked about.
