Solution

The correct option is A True
Cyanamide is an important organic chemical, which is used in agriculture and in the production of various pharmaceuticals and other organic compounds. It can be thought of as a nitrile group attached to an amine group.
Calcium Cyanamide is CaNCN, an inorganic compound that is extensively used as a fertilizer. It is synthesized by the famous Frank-Caro process (also known as the cyanamide process) where Calcium Carbide is heated with N2 gas in a reactor at 1273 K. The reaction is exothermic:
CaC2 + N2 CaNCN + C
( Calcium (Nitrogen) ( Calcium (Carbon)
Carbide) Cyanamide)
CaCN2 + 4H2O Ca(OH)2 + CO2 + 2NH3
(Calcium hydroxide) (Ammonia)
