Vedclass · Answer

(D) According to Fajan's rule,the covalent character of an ionic compound increases with the increase in the size of the anion.For a given cation $(Li^+)$,the polarizability of the anion determines the covalent character.The size of the halide ions follows the order: $F^- Since $I^-$ is the largest anion,it is the most polarizable,leading to the highest covalent character in $LiI$.
