Write the structures and names of the compounds formed when compound ‘A’ with molecular formula, C7H8 is treated with Cl2 in the presence of FeCl3.
When an arene is treated with Cl2 in presence of FeCl3, it undergoes chlorination to give aryl chloride by electrophilic addition reaction. Thus the compound given is C6H5—CH3, or toluene. On chlorination by electrophilic substitution, the products are o-chlorotoluene and p-chlorotoluene.
