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.

NH3 is definitely covalent. Hydrogen is an element that is sometimes placed on both the left side and the right side of the periodic table. One of the deficiencies of the rectangular table is that hydrogen doesn't really belong to a specific spot. Some other shapes and designs try to rectify this flaw. simple way to decide if a substance is covalent or ionic is to compare the electronegativities of the elements involved in the bonding. Electronegativity is a measure of the pull on shared electrons between to atoms.
