How bonding and structure are related to the properties of substances
Question
- A. Polymers have weaker covalent bonds.
- B. Polymers consist of smaller molecules.
- C. Polymers are linked by covalent bonds while small molecules are not.
- D. Polymers are made up of many covalent bonds compared to small molecules.
Answer
The correct option is Polymers are made up of many covalent bonds compared to small molecules.. This answer is correct because it matches the approved learning objective to recognise polymers from diagrams showing bonding and structure in the subtopic Polymers.
Explanation
The correct option is Polymers are made up of many covalent bonds compared to small molecules.. Polymers are made up of many covalent bonds compared to small molecules. is correct because it directly supports the approved learning objective to recognise polymers from diagrams showing bonding and structure. This belongs to the subtopic Polymers within How bonding and structure are related to the properties of substances, 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 Polymers.
Common mistake
Misidentifying Polymers
Students often confuse polymers with small molecules, failing to recognize the size and structure differences in diagrams.
Focus on identifying the repeating units and the large size of polymers in diagrams, and compare them to the simpler structures of small molecules.
