Reactions of alkenes and alcohols (chemistry only)

Question

A. They contain a double bond.
B. They are saturated compounds.
C. They contain the –OH functional group.
D. They are always gases at room temperature.

Answer

The correct option is They contain the –OH functional group..

Explanation

The correct option is They contain the –OH functional group.. They contain the –OH functional group. is correct because it directly supports the approved learning objective to recognise alcohols from their names or from given formulae. 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

Misidentifying Alcohols

Students often confuse alcohols with alkenes due to similar naming conventions.

Pay close attention to the functional group –OH in alcohols and remember that alcohols are not defined by a double bond like alkenes.
