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.

The given statement is true for aryl alkyl. The alkoxy group exhibits a (+ R) effect and due to this, the corresponding electron density in benzene ring starts to increase.
This can be be described by resonance structured that are available in chemistry books of class 11 and 12 syllabus.
So an electrophilic substitution is resulted and as the density keeps on increasing, towards the or-tho and the para positions respectively they tend to go towards those positions rather than sat the meta position in the benzene ring.
Hence it has been proven.
