Arrange the following alkyl halides in the decreasing order of SN2 reactivity.



(B) and (C) are primary and are very reactive, but bromide is more reactive than chloride.
(D) and (E) are both secondary but nucleophile attack on (D) is hindered because of stearic hindrance by two —CH3 group.

(A) is tertiary and therefore not reactive under SN2 conditions ;

(C) > (B) > (E) > (D) > (A).
