####50. Nitrogen (I) oxide is produced by

(a) thermal decomposition of $NH _4 NO _3$

(b) disproportionation of $N _2 O _4$

(c) thermal decomposition of $NH _4 NO _2$

(d) interaction of hydroxylamine and nitrous acid

Numerical Value

Solution:

  1. $NH _4 NO _3 \xrightarrow{\text { Heat }} N _2 O+2 H _2 O$

$NH _2 OH \cdot HCl+NaNO _2 \longrightarrow NaCl+2 H _2 O+N _2 O$

However, $NH _4 NO _2$ on heating gives $N _2$.
