Question
- A. It has a high melting point.
- B. It contains delocalised electrons.
- C. It is made of ionic bonds.
- D. It has a solid structure.
Answer
The correct option is It contains delocalised electrons.. This answer is correct because it matches the approved learning objective to explain that one electron from each carbon atom in graphite is delocalised in the subtopic Graphite.
Explanation
The correct option is It contains delocalised electrons.. It contains delocalised electrons. is correct because it directly supports the approved learning objective to explain that one electron from each carbon atom in graphite is delocalised. 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 Delocalised Electrons in Graphite
Students often think that all electrons in graphite are delocalised, rather than just one from each carbon atom.
Emphasize that in graphite, only one electron from each carbon atom is delocalised, allowing for conductivity.
