Explain the fact that in aryl alkyl ethers 

(i) The alkoxy group activates the benzene ring towards electrophilic substitution 

(ii) It directs the incoming substituents to ortho and para positions in benzene ring.

(i) In aryl alkyl ethers the +R effect of the alkoxy group leads to an increase in the electron density of the benzene ring as they push electrons into the ring making the benzene ring activated towards electrophilic substitution reactions. This could be understood more clearly from the follow
