(a) Ionic compounds conduct electricity in solution because they are made up of electrically charged ions but covalent compounds are made up of electrically neutral molecules so they do not conduct electricity.
(b) Conduct electricity: MgCl2, NaCl, Na2S (Ionic compounds)
Do not con duct electricity: CCl4, CS2 (Covalent compounds).
