22. If pK avalues of alcohol, water and phenol are 17, 14 and 10 respectively then which of the following reaction is possible :
a. 
b. 
c. 
d. None of these
Ans : (3)
The acidic character order is
alcohol< water < phenol
 basic charecter order for conjugate base is:
C 2H 5O -> OH -> C 6H 5O -.
The reaction in between one strong acid and other weak base or vice versa is possible.Also note that phenols are acidic in nature.
