Question

Identify the correct order of reactivity towards electrophilic substitution reactions of the following compounds. (A) 4 > 1 > 3 > 2 (B) 2 > 3 > 1 > 4 (C) 1 > 4 > 2 > 3 (D) 3 > 4 > 2 > 1

In electrophilic substitution reaction, electrophile

(E^{+})

is looking for an electron rich nucleus.

+ I

effect of

(C H_{3})_{3} C — > (C H_{3})_{2} C H —

— Cl

shows -I effect and

+ R

(or +M) effect.

— N O_{2}

shows

- I

effect and

- R

(or -M) effect. Hence the correct order towards SE reaction is

4 > 1 > 3 > 2

.
