Vedclass · Answer

(B) According to Fajan's rule,small cations with high charge have high polarizing power,leading to covalent character in ionic bonds.$Be^{2+}$ is a small cation with a high charge density compared to $Na^+$,$Li^+$,and $Rb^+$.Therefore,$BeCl_2$ exhibits significant covalent character,whereas $NaCl$,$LiCl$,and $RbF$ are predominantly ionic compounds.
