Why do alkyl halides show nucleophilic substitution reactions?

How aryl halides react with sodium metal? Explain why alkyl halides show nucleophilic substitution reaction ?

Explain, why. alkyl halides undergo nucleophilic substitution reaction?

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

Alkanes undergo free radical substitution, aromatic compounds undergo electrophilic substitution and alkyl halides undergo nucleophilic substitution reactions

Aryl halides are less reactive than alkyl halides towards nucleophilic substitution reactions because of :

From which of the following sequences does the reactivity of alkyl halides in the nucleophilic substitution reaction follows :
