Ionic compounds do not conduct electricity.
only when ionic compounds are broken into ions(by melting them at v. high temperatures or dissolving them into a solvent) they conduct electricity by displacement of ions.
covalent compounds do not conduct electricity because:
-unlike metals, they do not have free electrons to conduct electricity.
-unlike ionic compounds, they can not be broken up into two charged particles.
Covalent compounds can be conducting.........if dissociation is carried out!!
Even if you dissociate covalent compounds, what you get will be mere atoms, having no charge. you can't conduct electricity by displacing uncharged particles
Ionic compound in aqoues solution contains free ions which can conduct electricity whereas covalent compounds contain no free ions and cant confuct electricity
