Question
- A. A small molecule
- B. A large molecule made from repeating units
- C. A single atom
- D. A compound with a fixed formula
Answer
The correct option is A large molecule made from repeating units.
Explanation
The correct option is A large molecule made from repeating units. A large molecule made from repeating units is correct because it directly supports the approved learning objective to the simplest polymers are produced from two different monomers with two of the same functional groups on each monomer. This belongs to Polymerisation and naturally occurring polymers 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 Monomers and Polymers
Students often confuse monomers with polymers, thinking they are the same.
Remember that monomers are the small repeating units that join together to form polymers, which are large molecules made up of many monomers.
