Aromatic compounds are characterized by Electrophilic substitution reactions. The compound in which the attached group is EWG and shows -I and +M on benzene ring is

▬ OH group . . . - I , +M . . . EDG (+M > > -I)

$-{\mathrm{CH}}_3$ group . . . +I , +R . . . EDG

       -Cl group……-I, +M …….EWG(-I > +M)

$-{\mathrm{OCH}}_3$ group . . . - I , +M . . . EDG (+M > -I)

EDG increases the reactivity  towards ESR

Electron donating power of  $-\mathrm{OH}$ > $-{\mathrm{OCH}}_3$ > $-{\mathrm{CH}}_3$

$\therefore$ Reactivity towards ESR is (4) > (1) > (3) > (2)
