Vedclass · Answer

(A) According to $Fajan's$ rule,the covalent character of an ionic bond increases with an increase in the polarizing power of the cation.Polarizing power is directly proportional to the charge density of the cation (charge/size ratio).Comparing the cations: $Al^{3+}$,$Mg^{2+}$,$Cs^+$,and $La^{3+}$.$Al^{3+}$ has the smallest ionic radius and a high charge $(+3)$,resulting in the highest charge density.Therefore,$AlCl_3$ exhibits the maximum covalent character among the given options.
