The correct order of oxidation states of nitrogen in NO, N2O, NO2 and N2O3 respectively is
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → N2O < NO < N2O3 < NO2
Taking oxygen as −2, the oxidation state x of nitrogen in each oxide is:
N2O: 2x − 2 = 0, x = +1 — first
NO: x − 2 = 0, x = +2 — second
N2O3: 2x − 6 = 0, x = +3 — third
NO2: x − 4 = 0, x = +4 — last
