Vedclass · Answer

(C) According to Fajan's rule,the ionic character decreases as the covalent character increases. Covalent character increases with higher charge density on the cation (polarizing power). Comparing the compounds: $SnCl_4$ $(Sn^{4+})$ has the highest covalent character due to the high charge on the $Sn$ ion. $PbCl_2$ $(Pb^{2+})$ has more covalent character than $MgCl_2$ due to the larger size and inert pair effect. $MgCl_2$ $(Mg^{2+})$ is more ionic than $PbCl_2$ and $SnCl_4$. $KCl$ $(K^+)$ is the most ionic among these as it is an alkali metal halide. Thus,the increasing order of ionic character is: $SnCl_4 < PbCl_2 < MgCl_2 < KCl$.
