| Consider the following ions: |
| 1. \[NH_{2}^{-}\] |
| 2. \[C{{l}^{\,-}}\] |
| 3. \[ClO_{4}^{-}\] |
| 4. \[C{{H}_{3}}CO{{O}^{\,-}}\] |
| What is the correct order of basic strength of the above ions? |
A) 4 > 1 > 2 > 3
B) 4 > 3 > 1 > 2
C) 1 > 4 > 2 > 3
D) 1 > 4 > 3 > 2
Correct Answer: C
Solution :
Acid strength order \[HCl{{O}_{4}}>HCl>C{{H}_{3}}COOH>N{{H}_{3}}\] Conjugate base strength order \[Cl{{O}_{4}}^{-}>C{{l}^{-}}>C{{H}_{3}}CO{{O}^{-}}>N{{H}_{2}}^{-}\]
