Problem
A white crystalline solid 'A' on boiling with caustic soda solution gives a gas 'B', which on passing through an alkaline solution of potassium tetraiodomercurate (II) solution gives a brown ppt. The substance 'A' on heating evolves a neutral gas 'C', which is inert at room temperature and reactive in presence of catalyst and does not give brown fumes with nitric oxide.
The gas 'C' is:
(1) N2O
(2) O2
(3) NO
(4) N2
