How the stability of the oxidation states of group IV element vary down the group. (Illustrate your answer with the chloride of carbon and lead)
Oxidation state +2 become more stable down the group
Oxidation state +4 become less stable down the group.
This can be illustrated by chlorides of carbon and lead as follows:
CCl4 is stable whereas PbCl4 easily decomposes on heating giving lead (II) chloride and chlorine
PbCl4 (g) (heat) →PbCl2 (s) + Cl2 (g)
