Reactions of alkenes and alcohols (chemistry only)

Question

A. They are all gases at room temperature.
B. They all have a –COOH functional group.
C. They are all solids at room temperature.
D. They all contain a double bond.

Answer

The correct option is They all have a –COOH functional group..

Explanation

The correct option is They all have a –COOH functional group.. They all have a –COOH functional group. is correct because it directly supports the approved learning objective to describe what happens when any of the first four carboxylic acids react with alcohols. 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

Confusion Between Carboxylic Acids and Alcohols

Students often confuse the functional groups of carboxylic acids and alcohols, leading to incorrect descriptions of their reactions.

Review the functional groups: carboxylic acids contain –COOH, while alcohols contain –OH. Practice writing the reactions between them to reinforce understanding.
