The correct order of increasing reactivity of C-X bond towards nucleophile in the following compounds is: .

Answer»

(II)lt(III)lt(I)lt(IV)
(IV)lt(III)lt(I)lt(II)
(III)lt(II)lt(Ilt(IV)
(I)lt(II)lt(IV)lt(III)

Solution :ARYL HALIDES are less reactive towards nucleophilic substitutions reaction as compared to alkyl halides. In alkyl halides, involving `C-X` bond cleavage, (`S_(N^(1))` mechanism) the reactivity order is : `3^(@) GT 2^(@) gt 1^(@)` among the aryl halides the compound with electron withdrawing `-NO_(2)` group is more reactive as compared to simple aryl halide.t hus, the order of reactivity is:
(I)lt(II)lt(IV)lt(III).
