Structure and bonding of carbon
Question
- A. They are covalently bonded to each other
- B. They are held together by weak intermolecular forces
- C. They are made of ionic bonds
- D. They are metallic layers
Answer
The correct option is They are held together by weak intermolecular forces. This answer is correct because it matches the approved learning objective to explain that each carbon atom in graphite forms three covalent bonds in the subtopic Graphite.
Explanation
The correct option is They are held together by weak intermolecular forces. They are held together by weak intermolecular forces is correct because it directly supports the approved learning objective to explain that each carbon atom in graphite forms three covalent bonds. This belongs to the subtopic Graphite 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 Graphite.
Common mistake
Misunderstanding Carbon Bonds in Graphite
Students often state that each carbon atom in graphite forms four covalent bonds, similar to diamond.
Students should remember that each carbon atom in graphite forms three covalent bonds, allowing one electron to be delocalised.
