Q.
Identify the correct order of reactivity in electrophilic
substitution reactions of the following compounds
Benzene (1), Toluene (2), Chlorobenzene (3) and
Nitrobenzene (4)
Both chloro and nitro groups are deactivating in electrophilic
aromatic substitution reaction. Also nitro group is stronger
deactivating group. Methyl group is activator in electrophilic
aromatic substitution.
Hence, overall order of reactivity is :
nitrobenzene < chlorobenzene < benzene < toluene
