Chemistry · Phenols: Acidic nature, electrophilic substitution reactions, halogenation, nitration and sulphonation, Reimer Tiemann reaction
Which statement is INCORRECT.
Which statement is INCORRECT.
- A. Phenol has smaller dipolemoment than methanol.
- B. Haloarenes are insoluble in water but are soluble in benzene.
- C. Chloroform contains chlorine but gives no reaction with \( A g N O_{3} \) solution.
- D. Ethanol has much lower pka value than phenol.
Step-by-step solution
Phenol is more acidic than ethanol due to resonance stabilization of phenoxide ion. pKa of phenol is ~10, while ethanol is ~16, so ethanol has a higher pKa, not lower. Therefore, statement D is incorrect.
