NEET 2018 · ChemistryPrevious Year Question

The correct order of N-compounds in its decreasing order of oxidation states is

Answer: (C) $HNO X_{3}, NO, N X_{2}, NH X_{4} Cl$ . \textbf{Answer:} (C) $HNO X_{3}, NO, N X_{2}, NH X_{4} Cl$ .

A. $HNO X_{3}, NH X_{4} Cl, NO, N X_{2}$
B. $HNO X_{3}, NO, NH X_{4} Cl, N X_{2}$
C. $HNO X_{3}, NO, N X_{2}, NH X_{4} Cl$ ✓
D. $NH X_{4} Cl, N X_{2}, NO, HNO X_{3}$

Correct Answer

Solution & Explanation

\textbf{Answer:} (C) $HNO X_{3}, NO, N X_{2}, NH X_{4} Cl$ . \textbf{Solution:} Oxidation state of nitrogen in each species: $HNO X_{3}$ : $+ 5$ $NO$ : $+ 2$ $N X_{2}$ : $0$ $NH X_{4} Cl$ : $- 3$ Therefore the decreasing order of oxidation state is $HNO X_{3} > NO > N X_{2} > NH X_{4} Cl$ .
