Question:
Which of the following is most acidic?
Which of the following is most acidic?
Show Hint
Electron-withdrawing groups increase acidity by stabilizing the conjugate base through resonance (-M effect) and inductive (-I effect).
Updated On: Feb 25, 2025
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
p-Chlorophenol is the most acidic because:
- The Cl group is an electron-withdrawing group (-I effect), which stabilizes the conjugate base.
- This increases the acidity compared to normal phenol and other alcohols.
