Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The covalent character of ionic compound depends on polarising power of cation. Order of polarising power of cation is$\mathrm{B}{\mathrm{e}}^{++}>\mathrm{L}{\mathrm{i}}^{+}>\mathrm{N}{\mathrm{a}}^{+}$, Hence order of covalent character$\mathrm{B}\mathrm{e}\mathrm{C}{\mathrm{l}}_2>\mathrm{L}\mathrm{i}\mathrm{C}\mathrm{l}>\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}$.
