A) \[CaO+{{N}_{2}}\]
B) \[CaC+{{N}_{2}}\]
C) \[Ca{{C}_{2}}+N\]
D) \[Ca{{C}_{2}}+{{N}_{2}}\]
Correct Answer: D
Solution :
Nitrolim is prepared by heating finely powdered \[Ca{{C}_{2}}\] with a little of \[CaC{{l}_{2}}\] in the atmosphere of\[{{N}_{2}}\] at \[1000-{{1100}^{o}}C\], in an electric furnace \[Ca{{C}_{2}}+{{N}_{2}}\xrightarrow[(CaC{{l}_{2}})]{1000-{{1100}^{o}}C}\underset{\text{nitrolim}}{\mathop{[CaC{{N}_{2}}+C]}}\,\]
