Reactions of alkenes and alcohols (chemistry only)
Question
- A. Water and carbon dioxide
- B. Hydrogen and sodium alkoxide
- C. Oxygen and carbon monoxide
- D. Ethanol and carbon dioxide
Answer
The correct option is Water and carbon dioxide.
Explanation
The correct option is Water and carbon dioxide. Water and carbon dioxide is correct because it directly supports the approved learning objective to describe what happens when any of the first four alcohols react with sodium. This belongs to Alcohols within Reactions of alkenes and alcohols (chemistry only), so the answer must use the correct organic chemistry context. The other options are incorrect when they confuse the organic family, formula type, reaction condition, product, or property being tested. 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 Sodium Reactions
Students often think that all alcohols react with sodium in the same way, without considering the specific properties of each alcohol.
To fix this, students should study the individual reactions of methanol, ethanol, propanol, and butanol with sodium, noting any differences in reactivity or products formed.
