Structure and bonding of carbon
Question
- A. They have very high tensile strength.
- B. The correction should swap Graphene and fullerenes for an unrelated topic because all bonding models behave the same way.
- C. The correction should ignore the structure and focus only on naming a substance.
- D. The correction should use a general property statement without explaining the underlying particles or bonds.
Answer
They have very high tensile strength. This is the best correction because it separates the tested idea from nearby bonding or structure misconceptions.
Explanation
The correct answer is: They have very high tensile strength. This version tests misconception repair. It asks students to separate Graphene and fullerenes from nearby ideas in Structure and bonding of carbon, rather than treating them as interchangeable. The incorrect options either overgeneralise bonding models, ignore structure, or replace the explanation with a memorised label.
Common mistake
Confusing Carbon Nanotubes with Other Structures
Students often describe carbon nanotubes as flat structures instead of cylindrical.
Remember that carbon nanotubes are cylindrical fullerenes, emphasizing their shape and high length to diameter ratios.
