Current Question (ID: 8606)

Question:

$\text{The correct order of N-compounds in its decreasing order of oxidation states is:}$

Options:

1. $\text{HNO}_3\text{, NO, N}_2\text{, NH}_4\text{Cl}$
2. $\text{HNO}_3\text{, NO, NH}_4\text{Cl, N}_2$
3. $\text{HNO}_3\text{, NH}_4\text{Cl, NO, N}_2$
4. $\text{NH}_4\text{Cl, N}_2\text{, NO, HNO}_3$

Solution:

$\text{HNO}_3 \rightarrow 1+x-6=0; x=5$ $\text{NO} \rightarrow x-2=0; x=2$ $\text{N}_2 \rightarrow x=0$ $\text{NH}_4^+ \rightarrow x+4=1; x=-3$ $\text{Therefore, the decreasing order of oxidation states is: HNO}_3\text{(+5) > NO(+2) > N}_2\text{(0) > NH}_4\text{Cl(-3)}$
