Interpretation: The pairs that have higher oxidation number, nitrogen-containing ions, or nitrogen compound is to be chosen from the given options.
Concept Introduction: The oxidation number of the element is allocated based on the number of electrons gained or lost by the atom.
Answer to Problem 2STP
Correct answer: The correct option is ‘C’.
Explanation of Solution
Reason for correct option: In option I, the oxidation number of
In option III the oxidation number of
Therefore, equations I and III have a higher oxidation number of nitrogen ion than the nitrogen compound.
Reasons for incorrect options:
Option A is incorrect: Because equation I and II in both, the oxidation number of nitrogen ion is greater than the compound.
Option B is incorrect: In equation II,
Option D is incorrect: Because equation III agrees to the question statement but not in II.
Option E is incorrect: Because equation I and III agrees to the question statement but not equation II.
