Explain the fact that in aryl alkyl ethers (i) the alkoxy group activates the benzene ring towards electrophilic substitution and (ii) it directs the incoming substituents to ortho and para positions in benzene ring.

Why toluene is more reactive than benzene towards electrophilic substitution reactions?

Why toluene is more reactive than benzene towards electrophilic substitution reactions?

The typical reaction of benzene and other aromatic compounds is electrophilic substitution. Presence of electron donating group activates the ring towards electrophilic substitution, while presence of electron withdrawing group deactivates the ring towards electrophilic substitution but at the same time activates the ring towards nucleophilic substitution. Some groups are predominantly meta directing and all of these are deactivating. Except halogen, most of the o- and p- directing groups are activating groups. (E.A.S = Electrophilic aromatic substation) Presence of nitro group in benzene ring:
