The increasing order of reactivity of the following compounds towards reaction with alkyl halides directly is:

(i)

(ii) 

(iii)

(iv)

  1. i<ii<iii<iv
  2. ii<i<iii<iv
  3. ii<i<iv<iii
  4. i<iii<iv<ii

Solution

Alkyl halide undergoes nucleophilic substitution reaction. More nucleophilic nitrogen of amine group, more reactive will it be with alkyl halides.

Presence of electron-withdrawing group will decrease the nucleophilic character of amino group.

Hence the order of reactivity;
