Question
- A. Polymers are made up of ionic bonds.
- B. Polymers consist of small, discrete molecules.
- C. Polymers can have very high molecular weights.
- D. Polymers are always made from metals.
Answer
The correct option is Polymers can have very high molecular weights.. This answer is correct because it matches the approved learning objective to recognise that some covalent substances form very large molecules such as polymers in the subtopic Covalent bonding.
Explanation
The correct option is Polymers can have very high molecular weights.. Polymers can have very high molecular weights. is correct because it directly supports the approved learning objective to recognise that some covalent substances form very large molecules such as polymers. This belongs to the subtopic Covalent bonding within Chemical bonds, ionic, covalent and metallic, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Covalent bonding.
Common mistake
Misunderstanding Polymer Size
Students often think that all covalent substances are small molecules and do not recognize that some can form very large structures like polymers.
Emphasize that polymers are large molecules made of repeating units, and practice identifying examples of both small molecules and polymers.
