    Identify and justify the correct order of reactivity in electrophilic substitution in the following compounds:

    Answer:

                      The correct order of reactivity in electrophilic substitution is: The electrophile attack will be the easiest in case the ring is maximum activated out of the groups attached in different molecules. • \['C{{H}_{3}}'\] is highly activating due to hyper conjugation. • \['Cl'\] is activating due to resonance (R) effect but at the same time it is deactivating due to\[-I\]  effect. • \['N{{O}_{2}}'\]is deactivating in nature. In the light of the above observations, the order of reactivity is justified.
