Vedclass · Answer

(B) According to Fajan's rule, the covalent character of an ionic bond increases with an increase in the oxidation state of the metal cation.$1$. The oxidation states of the metal ions in the given compounds are: $SnCl_2$ $(Sn^{2+})$, $PbCl_4$ $(Pb^{4+})$, $SbCl_3$ $(Sb^{3+})$, and $PbCl_2$ $(Pb^{2+})$.$2$. $A$ higher positive charge on the cation results in greater polarizing power, which leads to more covalent character.$3$. Since $Pb^{4+}$ has the highest oxidation state among the given options, $PbCl_4$ exhibits the most covalent character.
