Which one of the following nitrogen oxides has the highest oxidation state of nitrogen?
General KnowledgeChemistry
- ANO
- BNO₂
- CN₂O
- DN₂O₅
Explanation
The oxidation states of nitrogen are: +2 in NO, +4 in NO2, +1 in N2O, and +5 in N2O5. Comparing these, +5 is the highest oxidation state nitrogen attains among the given oxides. N2O5 (dinitrogen pentoxide) is the anhydride of nitric acid, consistent with nitrogen's maximum +5 state. Hence N2O5 is the answer.
