Question

The correct order of the oxidation states of nitrogen in NO, N₂O, NO₂ and N₂O₃ is:
(A) N₂O < N₂O₃ < NO < NO₂ (B) NO₂ < NO < N₂O₃ < N₂O (C) NO₂ < N₂O₃ < NO < N₂O (D) N₂O < NO < N₂O₃ < NO₂

Answer 1

Option (C) is the correct answer.

NO2 < N2O3 < NO < N2O

Answer 2

option d)

in N2O oxidation sate of N2=1

in NO " " " " =2

In N2O3"""""""""""""=3

and in NO2""""""""=4

so option d) is the right one
