Chemistry Question on allotropes of carbon

Question

The bonding present between the carbon atoms of graphite:

Answer 1

Solution

In graphite, each carbon atom is $sp^{2}$ hybridised and is linked to three other carbon atoms directly in the same plane by covalent bond ( $\sigma$ bond) to form hexagonal ring. These rings constitute huge sheets. The different sheets are joined to each other by weak van der Waals' forces.
