Which of the following statements are correct? (i) Inductive effect and resonance effect is possible in chlorobenzene. (ii) Resonance effect dominates over inductive effect in anisole. (iii) p -nitrobenzoic acid is less acidic than m -nitrobenzoic acid. (iv) Diphenylamine is more basic than aniline.
Options
- A(i), (ii), (iii) and (iv)
- B(i) and (ii)
- C(iii) and (iv)
- D(i) and (iii)
Correct answer
B. (i) and (ii)
Step-by-step solution
(i) The Cl group activates benzene ring more by resonance effect. Cl group being more electronegative withdraws electrons from benzene ring and shows - I effect. (ii) The methyl group of ether can donate electrons through inductive effect that is not as strong as electron donation effect to the pi-system. So, resonance effect dominates over inductive effect in anisole. (iii) p -nitrobenzoic acid is more acidic than m -nitrobenzoic acid. When both acids donate H ⁺ from - COOH group, then p -nitrobenzoate is more sta
