Question

Nitrogen is not prepared in the laboratory by heating ammonium nitrile directly. Give reason. [2 Marks]

Answer 1

• On heating aqueous solution of ammonium nitrile, nitrogen is produced.
• But this decomposition of ammonium nitrile is very quick.
• Also, there is a chance of explosion if ammonium nitrile is heated alone.
• Therefore, nitrogen is not prepared in the laboratory by heating ammonium nitrile directly.
