| Match List I with List IILIST I (Amines) | LIST II(pKb ) |
|---|---|
| A | Aniline |
| B | Ethanamine |
| C | N-Ethylethanamine |
| D | N, N-Diethylethanamine |
| Choose the correct answer from the options given below: |
A-III, B-IV, C-II, D-I
A-III, B-II, C-IV, D-I
A-I, B-IV, C-II, D-III
A-III, B-II, C-I, D-IV
A-III, B-IV, C-II, D-I
Solution
The correct answer is (A) : A-III, B-IV, C-II, D-I
Amines are organic compounds that contain a nitrogen atom bonded to one or more alkyl or aryl groups. They are weak bases and react with acids to form salts.
The strength of a base is measured by its pKb value, which is the negative logarithm of its base dissociation constant (Kb). The higher the pKb value, the weaker the base.
List I contains the names of different amines, while List II contains their respective pKb values.
To match the amines with their correct pKb values, we need to compare their structures and the effects of the different alkyl or aryl groups attached to the nitrogen atom on their basicity.
