Four statements are given below. The correct statement is

Correct answer: C. oxidation state of N in NO and N2O5 is +2 and +5 respectively

  • A. oxidation state of N in NO and N2O5 is +5 and +2 respectively
  • B. oxidation state of N in NO and N2O5 is +1 and +5 respectively
  • C. oxidation state of N in NO and N2O5 is +2 and +5 respectively
  • D. oxidation state of N in NO and N2O5 is +2 and +4 respectively

Explanation

To determine the oxidation states of nitrogen (N) in compounds, you can use certain rules.In NO (nitric oxide), the oxidation state of nitrogen is usually -2. Since oxygen typically has an oxidation state of -2, and there is only one nitrogen atom in NO, the oxidation state of N is +2.In N2O5 (dinitrogen pentoxide), you can assign oxidation states based on the known oxidation states of oxygen (-2) and the overall charge of the molecule (0). In this case, nitrogen would have an oxidation state of +5.Correct. The oxidation state of N in NO is +2, and in N2O5, it is +5.Therefore, the correct statement is: c. oxidation state of N in NO and N2O5 is +2 and +5 respectively.

About Electrochemistry

Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
