The order of reactivity of the benzene rings toward the electrophilic substitution when it is substituted with an activating group increases as the substituents on the ring are groups that donate electrons.−CH3? is an activating group which makes benzene more reactive towards electrophile while −COOH is a deactivating group which makes it less reactive. The order reactivity towards the electrophilic substitution of the compounds

Toluene(I)>benzene(II)>Benzoic acid(III)
