Discuss nucleophilic substitution reaction `S_(N^(2)` of alkyl halide.

Elimination reactions (especially beta -elimination) are as common as the nucleophilic substitution reaction in case of alkyl halides. Specify the reagents used in both cases.

Aryl halides are less reactive in nucleophilic substitution reactions.Give one example for nucleophilic substitution reactions of aryl halides.

Explain why alkyl halides undergo nucleopilic substitution reaction more easily as compared to aryl halides ?

Explain S_N^2 reactions. What is the preference order of different alkyl halides to undergo nucleophilic substitution reaction via SN2 mechanism ?

Haloarenes are less reactive towards nucleophilic substitution reactions than haloalkanes. Give a reason.

Aryl halide are less reactive than alkyl halides towards nucleophilic substitution reactions. Why ?

Aryl halides are less reactive in nucleophilic substitution reactions. Write any two reasons for less reactivity.
