Question:
Which gas is evolved when Sodium metal reacts with Ethanol?
Which gas is evolved when Sodium metal reacts with Ethanol?
Show Hint
Active metals like sodium react with alcohols to release hydrogen gas by replacing the acidic hydrogen of the \(-OH\) group.
Updated On: Apr 29, 2026
- Oxygen
- Hydrogen
- Nitrogen
- Carbon dioxide
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Sodium reacts with ethanol by displacing the acidic hydrogen of the hydroxyl group, forming sodium ethoxide and hydrogen gas.
Step 1: Write the balanced chemical reaction. \[ 2C_2H_5OH + 2Na \rightarrow 2C_2H_5ONa + H_2 \]
Step 2: Identify the gas evolved. From the reaction, hydrogen gas (\(H_2\)) is released. \[ \boxed{H_2} \]
