Question

The compound that does not produce nitrogen gas by the thermal decomposition is:

Options

• Ba(N₃)₂

• (NH₄)₂Cr₂O₇

• NH₄NO₂

• (NH₄)₂SO₄

Answer 1

(NH₄)₂SO₄

Explanation:

Barium azide (Ba(N₃)₂), ammonium dichromate (NH₄)₂Cr₂O₇), and ammonium nitrite (NH₄NO₂) all produce nitrogen gas upon thermal decomposition due to the breakdown of nitrogen-containing groups. However, ammonium sulphate ((NH₄)₂SO₄) does not produce nitrogen gas when heated; instead, it decomposes to release ammonia and sulphur oxides without liberating (N₂) gas. Hence, (NH₄)₂SO₄ is the compound that does not produce nitrogen gas by thermal decomposition.
