Given below are two statements.
Statement I: Phenols are weakly acidic.
Statement II: Therefore they are freely soluble in NaOH solution and are weaker acids than alcohols and water.
Choose the most appropriate option:
  1. (A)Both Statement I and Statement II are correct.
  2. (B)Both Statement I and Statement II are incorrect.
  3. (C)Statement I is correct but Statement II is incorrect.✓ Correct
  4. (D)Statement I is incorrect but Statement II is correct.

Answer: (C)

Solution

Statement I is correct: Phenols are indeed weakly acidic due to resonance stabilization of the phenoxide ion. Statement II is incorrect: While phenols are soluble in NaOH solution (forming sodium phenoxide), they are MORE acidic than alcohols and water, not weaker. The order of acidity is: phenol > water > alcohol. Therefore, Statement I is correct but Statement II is incorrect. The answer is (C).
