Which of the following nitrates on heating does not give its oxide ?

Options

A. `LiNO_(3)`
B. `NaNO_(3)`
C. `Ba(NO_(3))_(2)`
D. `Be(NO_(3))_(2)`

Answer

B

Explanation

(a) `2LiNO_(3) underset(Delta) rarr Li_(2)O+N_(2)O_(5)`
(b) `underset("(Thermal stable)")(NaNO_(3)) underset(Delta) rarr` No product
(c ) `Ba(NO_(3))_(2) underset(Delta) rarr BaO +N_(2)O_(5)`
(d) `Be (NO_(3))_(2) underset(Delta) rarr BeO+N_(2)O_(5)`
`NaNO_(3)` is thermally stable and does not gives its oxide.
