Answer:
It is because of free electron in graphite.
Explanation: Graphite is a good conductor of electricity as each carbon atom is linked to three of its neighbouring carbon atoms. The fourth electon is free to move about. But diamond do not contain any free electon and all electrons are covalently bonded.

Both are allotropes of carbon. But due to their arrangement they differ in properties.
Graphite can conduct electricity because of the delocalised (free) electrons in its structure. ... However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.
