Hint: Calcium cyanamide is that the compound with the formula $CaC{{N}_{2}}$. it's the calcium salt of the cyanamide ($CN_{2}^{-2}$) anion. This chemical is employed as fertilizer. It was initially synthesised by Adolph Frank and Nikodem Caro in 1898.
Complete answer:
Calcium cyanamide is ready from the binary compound. The carbide powder is heated at about 1,100 °C in an electrical furnace into which nitrogen is passed for several hours, the merchandise is cooled to ambient temperatures and any unreacted carbide is leached out cautiously with water.
[\CaC{{N}_{2}}+3{{H}_{2}}O\xrightarrow{{}}2N{{H}_{3}}+CaC{{O}_{3}}\]
It was used to produce cyanide by fusing with sodium carbonate:
[\CaC{{N}_{2}}+N{{a}_{2}}C{{O}_{3}}+2C\xrightarrow{{}}2NaCN+CaO+2CO\]
Sodium cyanide is employed in the industrial process in gold mining. It also can be utilized in the preparation of calcium cyanide and melamine.
Through hydrolysis within the presence of $C{{O}_{2}}$, calcium cyanamide produces cyanamide:
\[CaC{{N}_{2}}+{{H}_{2}}O+C{{O}_{2}}\xrightarrow{{}}CaC{{O}_{3}}+{{H}_{2}}NCN\]
\[Ca{{C}_{2}}+{{N}_{2}}\xrightarrow{{}}CaC{{N}_{2}}+C\]
Additional information:
Calcium carbide, also known as calcium acetylide, is a chemical compound which contains the $Ca{{C}_{2}}$ chemical formula. Industrially its primary application is in the manufacture of acetylene and calcium cyanamide.
In India, nitrolime is not used. This fertiliser produces a high residual effect of basicity / salinity in the & soil that needs sulphur as a neutralizer. This fertiliser can be used in acidic soils where available.
Hence, the answer is option (c) Nitrolime
Note:
-The main use of calcium cyanamide is in agriculture as a fertilizer, on touch with water it decomposes and liberates ammonia.
- Nitrolime is a commercially accepted chemical compound also recognized as lime nitrogen.
