The correct order of acidity of above compounds is
- A II \( > \) IV \( > \) I \( > \) III
- B III \( > \) IV \( > \) II \( > \) I
- C IV \( > \) II \( > \) III \( > \) I
- D IV \( > \) III \( > \) I \( > \) II
Answer & Solution
Correct Answer
(D) IV \( > \) III \( > \) I \( > \) II
Step-by-step Solution
Detailed explanation
Hint : \(-\mathrm{NO}_2\) shows strong \(-\mathrm{R}\) \(-\mathrm{CH}=\mathrm{CH}_2\) shows \(-\mathrm{R}\) \(-\mathrm{CH}_3\) shows hyperconjugation \(-\mathrm{NMe}_2\) shows \(+\mathrm{R}\) Donating groups lowers acidity while withdrawing groups raise acidity
