Question:
Arrange the following in decreasing order of their acidity:
Arrange the following in decreasing order of their acidity:
Show Hint
Electron-withdrawing groups (\(-\text{NO}_2, -\text{CN}\)) increase acidity by stabilizing the conjugate base, while electron-donating groups decrease acidity.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Analyzing the effect of substituents on acidity.
- The acidity of benzoic acid derivatives is influenced by the electron-withdrawing or donating nature of the substituents.
- C (NO₂ group) is the most acidic due to the strong electron-withdrawing effect of \(-\text{NO}_2\).
- A (CN group) also withdraws electrons but is weaker than NO₂.
- B (F group) has an electron-withdrawing effect via induction but also donates via resonance, making it the least acidic among the three.
