The correct order of decreasing ionic character of PbF_(2),PbCl_(2),PbBr_(2) and PbI_(2) are

According to Fajans'rules, the percentage of covalent character in an ionic compound increase if the cation is highly charged or small in size and the anion is large or cation has pseudoinert gas configuration. As a result of the increased covalent character, solubility in less polar solvent increases and the melting point decreases. The correct order of increasing ionic character is
