dentify the incorrect statement about physical properties or phenol:
Correct answer: A. It is colourless crystalline molecular solid
- A. It is colourless crystalline molecular solid
- B. It is poisonous in nature
- C. It is used as a disinfectant in hospitals and washrooms
- D. It is sparingly soluble in water
Explanation
Phenol typically appears as a white crystalline solid, but it can also be colorless in its pure form. Therefore, this statement is incorrect as phenol is not a molecular solid in the same way that ionic or covalent solids are defined.

About Phenols
Phenols contain a hydroxyl group directly bonded to an aromatic ring, making them more acidic than alcohols because the phenoxide ion is resonance-stabilised. Reactions include ionisation with bases, electrophilic substitution, bromination, nitration and oxidation, with attention to the difference between phenols and aliphatic alcohols.
