Question

The product obtained as a result of a reaction of nitrogen with $CaC_2$ is

• A. ${CaCN }$
• B. ${CaCN3 }$
• C. ${Ca2CN }$
• D. ${Ca(CN)2 }$

Answer 1

The Correct Option is D

The given question involves a reaction between nitrogen (N_2) and calcium carbide (CaC_2). The problem requires finding the correct product formed from this reaction. Let's understand the reaction in detail:

1. **Reaction of Calcium Carbide with Nitrogen:**

- Calcium carbide reacts with nitrogen at high temperatures to form calcium cyanamide. The reaction is as follows:

\[ CaC_2 + N_2 \rightarrow Ca(CN)_2 \]

This is a well-known chemical reaction that results in the formation of calcium cyanamide, not to be confused with other compounds.

2. **Analysis of Options:**

• Option 1: CaCN - Incorrect. This is not a recognized product of the reaction of calcium carbide with nitrogen.
• Option 2: CaCN3 - Incorrect. This formula does not match the products from the given reaction.
• Option 3: Ca2CN - Incorrect. This compound does not exist in the context of the reaction.
• Option 4: Ca(CN)2 - Correct. This is calcium cyanamide, which matches the reaction product.

3. **Conclusion:**

- The product formed from the reaction of nitrogen with calcium carbide is calcium cyanamide, represented by the chemical formula Ca(CN)_2.

Therefore, the correct answer is: Ca(CN)_2.
