Structure and bonding of carbon
Question
- A. Layers of hexagonal rings with no covalent bonds between them.
- B. A single layer of carbon atoms.
- C. A solid mass of carbon atoms with strong bonds.
- D. A spherical arrangement of carbon atoms.
Answer
Layers of hexagonal rings with no covalent bonds between them.
Explanation
Graphite is structured in layers of hexagonal rings, and there are no covalent bonds between the layers, allowing them to slide over each other.
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.
