Structure and bonding of carbon
Question
- A. They are good electrical insulators.
- B. They have very high melting points.
- C. They can conduct electricity.
- D. They are soluble in water.
Answer
The correct option is They can conduct electricity.. This answer is correct because it matches the approved learning objective to explain that fullerene structures are based mainly on hexagonal rings and may include rings with five or seven carbon atoms in the subtopic Graphene and fullerenes.
Explanation
The correct option is They can conduct electricity.. They can conduct electricity. is correct because it directly supports the approved learning objective to explain that fullerene structures are based mainly on hexagonal rings and may include rings with five or seven carbon atoms. This belongs to the subtopic Graphene and fullerenes within Structure and bonding of carbon, 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 Graphene and fullerenes.
Common mistake
Confusing Fullerene Structure
Students often state that fullerenes are only made of hexagonal rings and do not mention the presence of pentagonal or heptagonal rings.
Emphasize that fullerene structures are primarily based on hexagonal rings but can also include rings with five or seven carbon atoms.
