The oxidation states of nitrogen in NO,NO2,N2ONO, {NO}_{2}, {N}_{2}O and NO3−{NO}_{3}^{-} are in the order of :

Options

  1. ANO3−>NO2>NO>N2O{NO}_{3}^{-} > {NO}_{2} > NO > {N}_{2}O
  2. BNO2>NO3−>NO>N2O{NO}_{2} > {NO}_{3}^{-} > NO > {N}_{2}O
  3. CN2O>NO2>NO>NO3−{N}_{2}O > {NO}_{2} > NO > {NO}_{3}^{-}
  4. DNO>NO2>N2O>NO3−NO > {NO}_{2} > {N}_{2}O > {NO}_{3}^{-}

Correct answer

A. NO3−>NO2>NO>N2O{NO}_{3}^{-} > {NO}_{2} > NO > {N}_{2}O

Step-by-step solution

The oxidation states of Nitrogen in following molecules are as follows

NO3−→+5{NO}_{3}^{-} \to + 5

NO2→+4{NO}_{2} \to + 4

NO→+2NO \to + 2

N2O→+1{N}_{2}O \to + 1
