A white crystalline solid (A) on boiling with caustic soda solution gave a gas (B), which when passed through an alkaline solution of potassium mercuric iodide gave brown ppt. The substance (A) on heating gave a gas (X)(\mathrm{X}), which rekindled a glowing splinter but did not give brown fumes with nitric oxide. The gas (B) isA white crystalline solid (A) on boiling with caustic soda solution gave a gas (B), which when passed through an

Options

  1. AH2 S\mathrm{H}_2 \mathrm{~S}
