Question

If Graphite is a Insulator then why it act as a Conductor?​

Answer 1

Explanation:

Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.

Answer 2

Graphite is good conductor of electricity because one carbon atom is bonded only three carbon atoms, which enables the presence of free electrons.
