The oxidation state of nitrogen (given in parentheses)is correct in all the following cases except A)HN₃ (-1). B)N₂O₃ (+3). C)HNO₃ (+5). D)NH₄⁺ (-3). E)N₂O (+1).

Question

Quizplus · Accepted Answer

In option A, the oxidation state of nitrogen in HNO2 should be +3 (considering the usual oxidation states of H as +1 and O as -2, the overall charge is 0, thus for NO2, N must be +3 to balance the -2 from each O and +1 from H). The given oxidation state of -1 is incorrect.
