The order of reactivity of phenol (I), nitrobenzene (II) and benzene (III) towards nitration is
Options
- A(III) > (I) > (II)
- B(II) > (III) > (I)
- C(I) > (III) > (II)
- D(I) > (II) > (III)
Correct answer
C. (I) > (III) > (II)
Step-by-step solution
Due to strong +R effect of - OH group, the electron density in phenol (I) is much more than in benzene (III) while due to the strong -R effect of the - NO ₂ group, the electron density in nitrobenzene (II) is much lower than in benzene. Hence, the order of reactivity towards nitration is as
