which among the following is not true for phenols?
select the correct answer below:
they possess hydroxyl groups on benzene rings.
they are more acidic than aliphatic alcohols.
they are more basic than aliphatic alcohols.
they lower the ph of water.

Explanation:

Phenols have hydroxyl groups on benzene rings (definition). Phenols are more acidic than aliphatic alcohols (due to resonance stabilization of phenoxide ion). Since they are acidic, they lower water's pH. Phenols are not more basic than aliphatic alcohols; in fact, they are more acidic. So the statement "They are more basic than aliphatic alcohols" is false.

Answer:

C. They are more basic than aliphatic alcohols.
