Answer:
Least acidic oxides of nitrogen are:
- Nitrous oxide (N₂O)
- Nitric Oxide (NO)
- Dinitrogen trioxide (N₂O₃)
- Dinitrogen tetraoxide (N₂O₄)
Most acidic oxide of nitrogen:
- Dinitrogen pentoxide (N₂0₅)
Explanation:
- The acidic nature of the oxides of nitrogen are determined by the strength of the acid formed by nitrogen oxide in water.
- Nitrogen reacts with oxygen to form nitrogen oxide.
- The oxidation states vary from +1 to +5.
- The nitrogen with higher oxidation state among the various nitrogen oxides are most acidic than that in lower oxidation state.
The oxidation number of various oxides of nitrogen:
- N₂O : +1
- NO : +2
- N₂O₃ : +3
- N₂O₄ : +4
- N₂O₅ : +5
Note:
As the oxidation state increases, the acidic nature of the oxide also increases. Therefore, the order of acidic strength is:
N₂O ≤ NO ≤ N₂O₃ ≤ N₂O₄ ≤ N₂O₅
