Vedclass · Answer

(D) The ionic character of metal halides follows the order $MF > MCl > MBr > MI$,where $M$ is a monovalent metal.According to Fajan's rule,the smaller the size of the anion,the greater is the ionic character of the bond.Since the fluoride ion $(F^-)$ is the smallest among the halide ions,it forms metal halides with the highest ionic character.

Which among the following halogens combines readily with metals to form metal halides with highest ionic character?
