Vedclass · Answer

(D) According to Fajan's rule,the covalent character of an ionic bond is directly proportional to the polarizing power of the cation and the polarizability of the anion.The polarizing power of a cation increases as its size decreases and its charge increases.Comparing the cations in the given compounds: $N^{3+}$ (in $NCl_3$),$O^{2+}$ (in $Cl_2O$),$Pb^{2+}$ (in $PbCl_2$),and $Ba^{2+}$ (in $BaCl_2$).Among these,$Ba^{2+}$ has the largest ionic radius and the lowest charge density.Since $Ba^{2+}$ has the lowest polarizing power,$BaCl_2$ exhibits the least covalent character and the highest ionic character.

Which of the following substances has the least covalent character?
