Question 10
Not true about phenol:
They are more basic than aliphatic alcohol
Explanation: actually, phenol is less basic than the aliphatic alcohol because electron pair of hydroxyl group take part in the resonance effect with the benzene ring system.

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....
