A metal burns in nitrogen to give an ionic compound . Compound reacts completely with water to give — s Block Elements Chemistry Question
Question
A metal $M$ burns in nitrogen to give an ionic compound $X$. Compound $X$ reacts completely with water to give a strongly basic solution $Y$ and a pungent-smelling colorless gas $Z$. The gas $Z$ forms a deep blue complex when passed through $CuSO_4$ solution. Identify the gas $Z$.
Answer: D
💡 Solution & Explanation
The metal forms a nitride ($M_3N_2$). Hydrolysis of an ionic nitride yields the metal hydroxide and Ammonia gas ($NH_3$). Ammonia reacts with aqueous $Cu^{2+}$ ions to form the deep blue tetraamminecopper(II) complex, $[Cu(NH_3)_4]^{2+}$.
