The diagrams show the structures of two allotropes of carbon: diamond and graphite.

Three-dimensional molecular structures of two allotropes of carbon. On the left, diamond has a tetrahedral giant covalent network structure where each carbon atom is bonded to four other carbon atoms. On the right, graphite has a layered structure containing hexagonal rings of carbon atoms, with weak dashed lines representing weak forces between the parallel layers.

a.

State two physical properties of diamond and two physical properties of graphite, excluding their electrical conductivity.

[4]
b.

State the type of chemical bonding holding the carbon atoms together within each layer of graphite.

[1]
c.

Explain why graphite conducts electricity but diamond does not, in terms of their structures and bonding.
