Question
What happens when ethanol reacts with sodium? Describe the reaction and any observations you would expect.
Answer
When ethanol reacts with sodium, it produces sodium ethoxide and hydrogen gas. The reaction is exothermic, and you would observe bubbles of hydrogen gas being released, and the sodium may dissolve in the ethanol.
Explanation
This question tests the understanding of the reactivity of alcohols with metals, specifically sodium. It assesses knowledge of the products formed and the observable changes during the reaction. This response is aligned to Alcohols because it explains investigate reactions of alcohols. (AT 2, 5, 6) using the correct AQA GCSE Chemistry organic context. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.

Common mistake
Misunderstanding Alcohol Reactions
Students often confuse the reactions of alcohols with those of alkenes, thinking they behave the same way in chemical reactions.
Focus on the functional group –OH in alcohols and remember that they undergo different reactions compared to alkenes, particularly in combustion and oxidation.
