The reaction of toluene with ${\mathrm{Cl}}_2$ in presence of ${\mathrm{FeCl}}_3$ gives predominantly :

1. m- chlorobenzene                   

2. benzoylchloride

3. benzyl chloride                         

4. O^- and p-chlorotoluene                    

On sulphonation of C₆H₅Cl, the product obtained is-

1. m-Chlorobenzene sulphonic acid is formed

2. Benzene sulphonic acid is formed

3. o-Chlorobenzene sulphonic acid is formed

4. o-and p-Chlorobenzene sulphonic acid is formed
