Identify the 'A' in the following reaction. CaC ₂ + H ₂ O A + Ca(OH) ₂

Options

AEthene
BEthyne
CPropene
DPropyne

Correct answer

B. Ethyne

Step-by-step solution

Calcium carbide reacts with water to form ethyne and calcium hydroxide. The balanced chemical equation is: CaC ₂ + 2 H ₂ O C ₂ H ₂ + Ca(OH) ₂ Thus, the product 'A' is ethyne ( C ₂ H ₂ ). Answer: Ethyne
