Vedclass · Answer

(A) According to Fajan's rule,as the size of the anion increases from $F^{-}$ to $I^{-}$,the polarizability of the anion increases,which leads to an increase in the covalent character of the lithium halide bond.Since non-polar solvents dissolve covalent compounds more readily than ionic compounds,the solubility in non-polar solvents increases as the covalent character increases.Therefore,the order of solubility is $LiI > LiBr > LiCl > LiF$.

The order of solubility of lithium halides in non-polar solvents follows the order:
