Question:
Explain the acidic nature of phenol.
Explain the acidic nature of phenol.
Show Hint
Phenols are weak acids due to delocalization of the negative charge on the oxygen in the conjugate base.

Solution and Explanation
Step 1: Resonance Stabilization:
\[
C_6H_5OH \rightleftharpoons C_6H_5O^- + H^+
\]
Phenol ionizes to release H\(^+\), stabilized by resonance.
Step 2: Stronger Acid than Alcohols:
- Phenol (\( pK_a = 9.95 \)) is more acidic than alcohols because of resonance stabilization.
- Phenol (\( pK_a = 9.95 \)) is more acidic than alcohols because of resonance stabilization.
