Among the following compounds (I - III), the correct order of reaction with electrophilic reagent is

A)  \[II>III>I\]

B)  \[III<I<II\]

C)  \[I>II>III\]

D)  \[I=II>III\]

Correct Answer: C

Solution :

Methoxy group being electron releasing group. It increases electron density of benzene nucleus while \[-N{{O}_{2}}\]   group being electron withdrawing, decreases the electron density of benzene nucleus. Hence, order of reaction with electrophilic reagent is
