Question:
Which of the following when subjected to thermal decomposition will liberate dinitrogen?
(i) sodium nitrate
(ii) ammonium dichromate
(iii) barium azide
Which of the following when subjected to thermal decomposition will liberate dinitrogen?
(i) sodium nitrate
(ii) ammonium dichromate
(iii) barium azide
Show Hint
Compounds containing azide (\( N_3^- \)) or ammonium cation (\( NH_4^+ \)) tend to release nitrogen gas upon decomposition.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Ammonium dichromate (\( (NH_4)_2Cr_2O_7 \)) decomposes to form N\(_2\), Cr\(_2O_3\), and H\(_2\)O.
Barium azide (Ba(N\(_3\))\(_2\)) decomposes to give Ba and N\(_2\) gas.
Sodium nitrate (NaNO\(_3\)) decomposes into NaNO\(_2\) and O\(_2\), not N\(_2\).
