Q. $S_N2$ mechanism is involved in the following substitution :

Haloalkanes and Haloarenes

Solution:

${S_N2}$ mechanism is followed in the case of primary and secondary alkyl halides, but primary is more reactive than secondary i.e. In comparision to p-halides reactivity of s-hlides towards ${S_N2}$ reaction is negligible.
