Question
- A. Presence of delocalised electrons.
- B. Absence of mobile charged particles.
- C. Presence of ionic bonds.
- D. High density of carbon atoms.
Answer
The correct option is Absence of mobile charged particles.. This answer is correct because it matches the approved learning objective to explain why diamond does not conduct electricity in the subtopic Diamond.
Explanation
The correct option is Absence of mobile charged particles.. Absence of mobile charged particles. is correct because it directly supports the approved learning objective to explain why diamond does not conduct electricity. This belongs to the subtopic Diamond 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 Diamond.
Common mistake
Misunderstanding Electrical Conductivity
Students often think that diamond conducts electricity because it is a solid and has a regular structure.
Emphasize that diamond does not have free-moving charged particles, such as delocalised electrons, which are necessary for electrical conductivity.
