The correct order of reactivity towards the electrophilic substitution of the compounds aniline (I), benzene (II) and nitrobenzene (III) is
- AIII > II > I
- BII > III > I
- CI < II > III
- DI > II > III
View written solutionFree
Correct answer: D
–NH2 group is electron donating hence increases electron density on ring. Benzene is also electron rich due to delocalisation of electrons. –NO2 group is electron withdrawing hence, decreases electron density on ring. Thus, correct order for electrophilic substitution is I $\gt $ II $\gt $ III.
