Which of the following is most basic ?
Show Hint
- \(Mn_2O_7\)
- \(MnO_2\)
- \(MnO\)
- \(Mn_2O_3\)
The Correct Option is C
Solution and Explanation
For oxides of the same metal, basic character increases as the oxidation state of the metal decreases. Lower oxidation state oxides are more basic, while higher oxidation state oxides are acidic.
Step 1:
Find the oxidation state of Mn in each oxide: \(Mn_2O_7\) is +7 (acidic), \(MnO_2\) is +4 (amphoteric), \(Mn_2O_3\) is +3, and \(MnO\) is +2.
Step 2:
The lowest oxidation state (+2) gives the most basic oxide, which is \(MnO\).
Answer: Option (C) \(MnO\) is the most basic oxide.
