Reactions of alkenes and alcohols (chemistry only)
Question
- A. They are strong acids.
- B. They contain the –COOH functional group.
- C. They are always gaseous at room temperature.
- D. They do not dissolve in water.
Answer
The correct option is They contain the –COOH functional group..
Explanation
The correct option is They contain the –COOH functional group.. They contain the –COOH functional group. is correct because it directly supports the approved learning objective to describe carboxylic acids as compounds that contain the functional group –COOH. This belongs to Carboxylic acids 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
Confusing Functional Groups
Students often confuse carboxylic acids with alcohols, thinking both contain the same functional group.
Remember that carboxylic acids contain the –COOH functional group, while alcohols contain the –OH functional group. Focus on the distinct structures and properties of each.
