We have three types of intramolecular forces:
Ionic bonds - Covalent bonds and metallic bonds
Ionic bond conductivity:
solid state : bad conductor
Liquid or molten state : good conductor due to the movement of free ions.
Covalent bond conductivity:
Poor conductor in solid or liquid state due to molecules are not normally ionized
Metallic bond:
Good conductor on solid state due to the presence of free electrons
