Which of the following tests may be used to distinguish between phenol and cyclohexanol?

Options

  1. AHinsberg test
  2. BIodoform test
  3. CReaction with Na metal
  4. DFerric chloride test

Correct answer

D. Ferric chloride test

Step-by-step solution

Phenol is an aromatic compound containing a hydroxyl group attached directly to a benzene ring, which imparts acidic character to the molecule. Cyclohexanol is an aliphatic cyclic alcohol. The ferric chloride test is a characteristic test for phenols. Phenols react with neutral ferric chloride solution to form a violet, green, or blue colored complex, which is due to the formation of iron-phenolate complexes. Cyclohexanol, being an aliphatic alcohol, does not give this test. The Hinsberg test is used to distinguish
