Which one of the following properties is not true for graphite?
- Hybridization of each carbon atom is sp3
- Hybridization of each carbon atom is sp2
- Electrons are delocalized over the whole sheet of atoms
- Each layer is composed of hexagonal rings
In graphite, each carbon atom is sp2 hybridised and is bonded to three other carbon atoms through a σ bond. The fourth electron forms a π bond.
The correct option is A.
