A compound (X) on heating with an excess of NaOH solution gives a gas (Y) which gives white fumes on exposure to HCl. Heating is continued to expel the gas completely. The resultant alkaline solution again liberates the same gas (Y) when heated with Zn powder. However, when the compound (X) is heated alone does not give nitrogen. Identify (X) and (Y).

On heating with concentrated NaOH solution in an inert atmosphere of CO_(2) , white phosphorus gives a gas. Which of the following statements is incorrect about the gas ?

A white crystalline solid (A) on boiling with caustic soda solution gave a gas (B) which when passed through an alkaline solution of K_(2) [HgI_(4)] gave a brown precipitate. The substance (A) on heating gave a gas (X) which rekindled a glowing splinter but does not give brown fumes with nitric oxide. The gas (X) is:
