Question

Among the following amines, which one has the highest
pKb value in aqueous solution?
(a) Methanamine (b) N,N-Dimethylaniline
(c) Ethanamine (d) Benzenamine

Answer 1

Explanation:

d) Benzenamine has highest pkb value

Answer 2

Among the following amines, 'Benzenamine' has the highest pKb value in aqueous solution.

Option: (d)

Explanation:

• Usually, Amines react with acids to form salts. Amine salts are soluble in water which can be insoluble in organic solvents.
• The base character of amines can be better explained in terms of their Kb and pKb values.
• Larger the value of Kb or smaller the value of pKb, stronger is the base. The ammonia value of pKb is 4.75. The Benzenamine has the pKb value of 9.38.
