Answer:
Ionic bonds are weak, so, when they are dissolved in solvents, their intermolecular force of attraction between the bonds get weaken, hence, they form ions. Whereas, covalent compounds do not have the ability to form ions.
Only MgCl2 and NaCl will conduct electricity because they are ionic compounds. Others will not conduct electricity because they are covalent compounds.
