State reasons for the following:The N - O bond in NO_2^(-) is shorter – InterviewSolution

1.	State reasons for the following:The N - O bond in NO_2^(-) is shorter than the N - O bond in NO_3^(-).
Answer» SOLUTION :Oxidation state of N in `NO_2^(-)` is +3 while the oxidation state of N in `NO_3^(-)` is +5 . Due to this difference, N-O BOND in `NO_2^(-)` is shorter than the N-O bond in `NO_3^(-)`.
