Question

which of the following compound of group-14 elements would you expect to be most ionic in character? (1) CCl4 (2) SiCl4 (3) PbCl2 (4) PbCl4

Answer 1

Answer:

1

Explanation:

as we move down in a group Polarisability increases therefore covalent character increases and ionic character decreases , also electronegativity decreases down the group so covalent character increases .

Answer 2

Answer:

(3) PbCl12

Explanation:

PbCl2 is most ionic because on going down the group the metallic character increases and also the inert pair effect predominates. Higher the oxidation state, more is the covalent character
