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.
