Q. The products obtained on heating $LiNO_{3}$ will be
A) $LiNO_{2} + \ O_{2}$
B) $Li_{2}O + NO_{2} + \ O_{2}$
C) $Li_{3}N + O_{2}$
D) $Li_{2}O + OH + O_{2}$
Explanation
(b)
$LiNO_{3}$ behaves differently from other alkali metal nitrates.
$2LiNO_{3}\overset{\ \ \ \ \ \mathrm{\Delta}\ \ \ \ \ }{\rightarrow}\ Li_{2}O + 2NO_{2} + \frac{1}{2}O_{2}$
$NaNO_{3}\overset{\ \ \ \ \ \mathrm{\Delta}\ \ \ \ \ }{\rightarrow}\ NaNO_{2} + \frac{1}{2}O_{2}$
