Read the passage given below and answer the following questions:
Aryl halides are extremely less reactive towards nucleophilic substitution reactions due to the following reasons:
(i) In haloarenes, the electron pairs on halogen atom are in conjugation with u-electrons of the ring.
(ii) In haloalkane, the carbon atom attached to halogen is `sp^3` hybridised while in case of haloarene, the carbon atom attached to halogen is `sp^2` -hybridised.
In case of haloarenes/ the phenyl cation formed as a result of self-ionisation will not be stabilised by resonance.
