Vedclass · Answer

(D) In the presence of heat (boiling point conditions) or $UV$ light,chlorine reacts with the side chain of toluene via a free radical substitution mechanism. When excess $Cl_{2}$ is used,it leads to the progressive substitution of all three hydrogen atoms on the methyl group. The reaction proceeds as follows: $C_6H_5CH_3$ $\xrightarrow{Cl_2, \Delta} C_6H_5CH_2Cl$ $\xrightarrow{Cl_2, \Delta} C_6H_5CHCl_2$ $\xrightarrow{Cl_2, \Delta} C_6H_5CCl_3$. Thus,the final product is $C_6H_5CCl_3$,which is known as trichloromethylbenzene or benzotrichloride.
