Which properties is not true for graphite

• GC Chemical Bonding

Which one of the following properties is not true for graphite?

1. Hybridization of each carbon atom is sp³
2. Hybridization of each carbon atom is sp²
3. Electrons are delocalized over the whole sheet of atoms
4. Each layer is composed of hexagonal rings

Answer

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.
