Question

The cyanamide process is used in formation of
A. ${N_2}$
B. $HN{O_3}$
C. $N{H_3}$
D. $P{H_3}$

Answer 1

Hint: Cyanamide being a derivative of nitrogen is a common intermediate in reactions that are used to form nitrogen compounds. It has a molecular formula of $CaC{N_2}$ . It also contains carbon.

Complete step by step answer:
The cyanamide process is a process of formation of Cyanamide as a transient, intermediate compound during the formation of nitrogen compounds. The cyanamide process is a common process which is used for the formation of Ammonia. The reaction can be represented as follows:

$Ca{C_2} + {N_2} \to CaC{N_2} + C$

The first reaction in the formation of ammonia through cyanamide processes the formation of cyanamide. This is demonstrated above where in calcium carbide $Ca{C_2}$ is made to react with Nitrogen. This forms cyanamide. It is an exothermic reaction.
The second step shown below is the reaction of cyanamide with water.

$CaC{N_2} + {H_2}O \to N{H_3} + CaC{O_3}$

This reaction demonstrates the hydrolysis of cyanamide to form ammonia and calcium carbonate. Therefore the answer to the question will be option c. That in the cyanamide process is employed for the release of ammonia gas.
Cyanamide is also known as Nitrolium when another is taken separately. This means that the molecular formula will be
$CaC{N_2} + C$ . it can also be represented in the bond formation as shown below:
$\left[ {C{a^{ + 2}}} \right]$ $^ - N = C = {N^ - }$ . This shows that there is an unsaturated bond between nitrogen and carbon.
This compound is also used as a fertilizer to help increase the concentration of nitrogen for the plants.
The other compounds mentioned in the other options will not be formed using this process.

So, the correct answer is Option C .

Note: The cyanamide process is used to produce ammonia on a commercial scale. It was later replaced by Haber's process. The process involves first the formation of cyanamide and this cyanamide is later hydrolysed to form the ammonia required.
