Q44 / 150 · MHT CET 2026 (17 April Shift 2) · Chemistry
Identify the 'A' in the following reaction.
$\text{CaC}_2 + \text{H}_2\text{O} \rightarrow \text{A} + \text{Ca(OH)}_2$
$\text{CaC}_2 + \text{H}_2\text{O} \rightarrow \text{A} + \text{Ca(OH)}_2$
- AEthene
- Correct answerBEthyne
- CPropene
- DPropyne
Solution
Calcium carbide reacts with water to form ethyne and calcium hydroxide.
The balanced chemical equation is:
$\text{CaC}_2 + 2\text{H}_2\text{O} \rightarrow \text{C}_2\text{H}_2 + \text{Ca(OH)}_2$
Thus, the product 'A' is ethyne ($\text{C}_2\text{H}_2$).
Answer: Ethyne
The balanced chemical equation is:
$\text{CaC}_2 + 2\text{H}_2\text{O} \rightarrow \text{C}_2\text{H}_2 + \text{Ca(OH)}_2$
Thus, the product 'A' is ethyne ($\text{C}_2\text{H}_2$).
Answer: Ethyne
Hence, the correct answer is option: 'B'.
