why does graphene conduct electricity?
usually covalent structures cannot conduct electricity but graphene is one of the exceptions and this is due to its structure and bonding. It is a giant covalent 2D molecule, hexagonal in shape with 3 covalently bonded carbon atoms. the fourth carbon atom is delocalised which allows it to act a mobile charge carrier and allowing electrical conductivity.
