Structure and bonding of carbon
Question
- A. It has delocalised electrons that can move freely
- B. It has a metallic structure
- C. It has a high density of ions
- D. It has strong covalent bonds
Answer
The correct option is It has delocalised electrons that can move freely. This answer is correct because it matches the approved learning objective to explain graphite's properties using its structure and bonding in the subtopic Graphite.
Explanation
The correct option is It has delocalised electrons that can move freely. It has delocalised electrons that can move freely is correct because it directly supports the approved learning objective to explain graphite's properties using its structure and bonding. 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 Graphite's Conductivity
Students often state that graphite conducts electricity because it has free electrons, without specifying that these electrons are delocalised.
Emphasize that in graphite, one electron from each carbon atom is delocalised, allowing it to conduct electricity.
