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 increasedcovalent character, solubility in less polar solvent increases and the melting point decreases. The correct order of increasing ionic character is

Answer» `Be Cl _(2) lt Mg Cl_(2) lt CaCl_(2) lt BaCl_(2)` `Be Cl_(2) lt MgCl_(2) lt BaCl_(2)lt CaCl_(2)` `BeCl_(2) lt BaCl_(2) lt MgCl_(2) lt CaCl_(2)` `BaCl_(2) lt CaCl_(2) lt MgCl_(2) lt BeCl_(2)` Solution :Ionic character of clorides increases as the size of the action increase (Frajan's rules) from `Be ^(2+)` to `Ba^(2+).`
