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.

So why do... show more I thought that since the difference in electronegativity is only 0.02, that AsH3's bonds are covalent. Since AsH3 is covalent, the electrons are shared evenly so no dipole results. A polar bond refers to an unequal sharing of electrons and a polar molecule needs to have polar bonds.wo possible reasons As is under N and NH3is a prime example of a polar molecule As has a tetrahedral orbital geometry, but a pyramidal molecular geometry. That means there is an unshared electron pair with a negative charge hanging off one side of the molecule.
