Vedclass · Answer

(B) An addition reaction involves the combination of two or more molecules to form a larger molecule without the loss of any atoms. $A$. Hydrogenation of benzene is an addition reaction where $3$ moles of $H_2$ add to the benzene ring. $B$. The reaction of benzene with $Cl_2$ in the presence of a Lewis acid catalyst like $AlCl_3$ in the dark is an electrophilic substitution reaction,not an addition reaction. In this process,hydrogen atoms on the benzene ring are replaced by chlorine atoms. $C$. Ozonolysis of benzene is an addition reaction. $D$. Chlorination of benzene in the presence of sunlight $(h
u)$ is a free-radical addition reaction. Therefore,option $B$ is not an addition reaction.
