Question

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

• A. $CC{l}_4$
• B. $SiC{l}_4$
• C. $PbC{l}_2$

Answer 1

Answer: (C)

$PbC{l}_2$ is most ionic because on going down the group the metallic character increases and also the inert pair effect predominates.
