Question
- A. Cellulose
- B. Starch
- C. Protein
- D. Polyethylene
Answer
The correct option is Polyethylene.
Explanation
The correct option is Polyethylene. Polyethylene is correct because it directly supports the approved learning objective to other naturally occurring polymers important for life include proteins, starch and cellulose. 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 Types of Polymers
Students often confuse proteins, starch, and cellulose as synthetic polymers rather than naturally occurring ones.
Remember that proteins, starch, and cellulose are naturally occurring polymers made from biological monomers, while synthetic polymers are man-made.
