Which of the following statements is NOT true about phenol?
Select the correct answer below:
The aromatic ring delocalizes and stabilizes the negative charge on the oxygen in the phenoxide ion. Therefore, phenols completely dissociate in water.
A phenol will generally form stronger hydrogen bonds than nonaromatic alcohols because the oxygen-hydrogen dipole in the hydroxyl group is stabilized by resonance from the aromatic ring.
The phenol functional group is a weak acid in water because the hydroxyl group dissociates slightly.
All of the above statements are incorrect.
