JEE Main levelSingle correct optionDifficulty 2 of 3pn175

Ammonium nitrate is heated gently to about 520 K. The gas evolved and the oxidation state of nitrogen in it are

A $N X_{2} O$ and $+ 1$
B $NO X_{2}$ and $+ 4$
C $NO$ and $+ 2$
D $N X_{2}$ and $0$

Answer: A

Gentle heating gives

NH X_{4} NO X_{3} N X_{2} O + 2 H X_{2} O

. The N atoms at

- 3

(ammonium) and

+ 5

(nitrate) end up at

+ 1

in

N X_{2} O

since

(- 3 + 5) /2 = + 1

.
