How bonding and structure are related to the properties of substances
Question
- A. They make polymers more flexible than small molecules
- B. They allow polymers to conduct electricity
- C. They contribute to polymers being solids at room temperature
- D. They make polymers easier to melt than small molecules
Answer
The correct option is They contribute to polymers being solids at room temperature. This answer is correct because it matches the approved learning objective to explain that intermolecular forces between polymer molecules are relatively strong compared with many small molecules in the subtopic Polymers.
Explanation
The correct option is They contribute to polymers being solids at room temperature. They contribute to polymers being solids at room temperature is correct because it directly supports the approved learning objective to explain that intermolecular forces between polymer molecules are relatively strong compared with many small molecules. 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
Misunderstanding Intermolecular Forces in Polymers
Students often think that intermolecular forces in polymers are weak like those in small molecules.
Emphasize that intermolecular forces between polymer molecules are relatively strong compared to many small molecules.
