Structure and bonding of carbon

Question

A. It has strong covalent bonds throughout the structure.
B. It has weak intermolecular forces.
C. It contains delocalised electrons.
D. It is made of small molecules.

Answer

The correct option is It has strong covalent bonds throughout the structure.. This answer is correct because it matches the approved learning objective to explain why graphite conducts electricity in the subtopic Graphite.

Explanation

The correct option is It has strong covalent bonds throughout the structure.. It has strong covalent bonds throughout the structure. is correct because it directly supports the approved learning objective to explain why graphite conducts electricity. 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 Conductivity in Graphite

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.
