Which gas is liberated when ethanol reacts with sodium metal?
AOxygen
BHydrogen
CCarbon dioxide
DMethane
Answer & Solution
Correct answer: B. Hydrogen
1. Highly reactive sodium reacts with the -OH group of ethanol.
2. The products are sodium ethoxide and a gas.
3. The reaction 2Na + 2CH3CH2OH gives 2CH3CH2ONa + H2, liberating hydrogen gas.
4. Rule out C: carbon dioxide is released when ethanoic acid reacts with carbonates, not from ethanol plus sodium.
