  Which of the following compounds is the weakest Bronsted base? (a)                       (b)                          (c)                           (d)

Answer:

                  (c) Amines (a, b) have a stronger tendency to accept a proton and hence are stronger Bronsted bases than phenol (c) and alcohol (d). Since phenol is more acidic than alcohol, therefore, phenol (c) has the least tendency to accept a proton and hence it is the weakest Bronsted base.
