Answer:
Aryl halides are relatively unreactive toward nucleophilic substitution reactions. This lack of reactivity is due to several factors. Steric hindrance caused by the benzene ring of the aryl halide prevents S N2 reactions. Likewise, phenyl cations are unstable, thus making S N1 reactions impossible.

Answer:
SN1 r SN2 are not possible in case of aryl halides.
Explanation: This is because in case of SN2 type of reactions, the nucleophile attacks from backside. Due to larger size of phenyl ring, nucleophilic attack is not feasible due to steric factor. Hence SN2 is not possible.
SN1 in aryl halides are also not possible due to generation of a unstable phenyl cation as an intermediate, it will prevent from SN1 of aryl chrorides.
