Question
Which of the following compounds is the weakest Brönsted base?
Options
Advertisements
Solution
Explanation:
Amines (i, ii) have stronger tendency to accept a proton and hence are stronger Bronsted bases than phenol (iii) and alcohol (iv). Since phenol is more acidic than alcohol, therefore, phenol (iii) has the least tendency to accept a proton and hence it is the weakest Bronsted base.
