The CORRECT order of N-compounds in its decreasing order of oxidation states is _________.

  1. A
    \( \text{HNO}_3\text{, NO, N}_2\text{, NH}_4\text{Cl} \)
  2. B
    \( \text{HNO}_3\text{, NO, NH}_4\text{Cl, N}_2 \)
  3. C
    \( \text{HNO}_3\text{, NH}_4\text{Cl, NO, N}_2 \)
  4. D
    \( \text{NH}_4\text{Cl, N}_2\text{, NO, HNO}_3 \)
View Answer & Solution

Correct answer · Option A

\( \text{HNO}_3\text{, NO, N}_2\text{, NH}_4\text{Cl} \)

Explanation

Oxidation states of N in \( \text{HNO}_3 \) is +5, in \( \text{NO} \) is +2, in \( \text{N}_2 \) is 0, and in \( \text{NH}_4\text{Cl} \) is -3. Thus, decreasing order is \( \text{HNO}_3 > \text{NO} > \text{N}_2 > \text{NH}_4\text{Cl} \).
