Vedclass · Answer

(C) The ionic character of a compound depends on the electronegativity difference between the bonded atoms and the oxidation state of the metal.As we move down group $14$,the metallic character of the elements increases,which enhances the ionic nature of their halides.Additionally,due to the inert pair effect,the lower oxidation state $(+2)$ becomes more stable for heavier elements like $Pb$.$PbCl_2$ involves $Pb$ in the $+2$ oxidation state,which is more ionic compared to the covalent $PbCl_4$ (where $Pb$ is in the $+4$ state) and the covalent halides of lighter elements like $C$ and $Si$.Therefore,$PbCl_2$ is the most ionic compound among the given options.

Which of the following compounds of elements in group $14$ would you expect to be most ionic in character?
