QJEEM18Chc93f: JEE Main 2018 Chemistry - Class 12 JEEM18Chc93f Solution: The compound that does not produce nitrogen gas by the thermal…

Thermal decomposition reaction of the given compounds are . . .

(NH₄)₂SO₄ $$\stackrel{\mathrm{\Delta }}{⟶}$$ 2 NH₃(g) + H₂SO₄

Ba (N₃)₂ $$\stackrel{\mathrm{\Delta }}{⟶}$$ Ba + 3N₂(g)

NH₄NO₂ $$\stackrel{\mathrm{\Delta }}{⟶}$$ N₂(g) + 2H₂O

(NH₄)₂Cr₂O₇ $$\stackrel{\mathrm{\Delta }}{⟶}$$ N₂(g) + 4H₂O + Cr₂O₃

So, here you can see only (NH₄)₂SO₄ does not give N₂ by thermal decomposition it gives NH₃ while other give N₂ gas
