is alcl3 ionic or covalent
AlCl3 is basically an ionic compound, but according to Fajan's rules, every ionic compound has some covalent character in it. From the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation.Now Al3+ has high +ve charge on it, so it can distort the cl-cation easily, thus inducing covalent character into it.See Wikipedia for more details.rom the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation.
