Vedclass · Answer

(D) According to Fajan's rule,covalent character increases as the size of the anion increases for a fixed cation.The polarizability of the anion increases with its size,leading to greater distortion of the electron cloud by the cation.The size of the halide ions follows the order: $F^- Since $I^-$ is the largest anion among the given options,it is the most polarizable.Therefore,$CaI_2$ exhibits the highest covalent character.
