Identify the 'A' in the following reaction.
\(\text{CaC}_2+\text{H}_2\text{O}\rightarrow \text{A}+\text{Ca(OH)}_2\)
\(\text{CaC}_2+\text{H}_2\text{O}\rightarrow \text{A}+\text{Ca(OH)}_2\)

- Ethene
- Ethyne
- Propene
- Propyne
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Balance carbon and hydrogen:
$\text{CaC}_2$ has 2 carbons. Two water molecules supply 2 H to carbon and 2 OH to calcium.
Step 2: Product:
The two hydrogens go on the two carbons, giving $\text{H-C}\equiv\text{C-H}$, ethyne (B).
Final Answer:
Ethyne. \[ \boxed{\text{(B)}} \]
