Options
- AA-I, B-IV, C-II, D-III
- BA-III, B-II, C-I, D-IV
- CA-III, B-II, C-IV, D-I
- DA-III, B-IV, C-II, D-I
Correct answer
D. A-III, B-IV, C-II, D-I
Step-by-step solution
Among given aliphatic amines, 2° amine is most basic, followed by 3° amine and 1° amine. Therefore, the correct basic strength (K b ) order of the given amines is (C) > (D) > (B) > (A) The pK b order of the given amines will be just the opposite of their basic strength order. The order is (A) > (B) > (D) > (C) So the correct answer is A-III, B-IV, C-II, D-I
