Why is pbcl4 is less stable than sncl4

1.	Why is pbcl4 is less stable than sncl4
Answer» The stability of higher oxidation state decrease down the group whereas the stability of lower oxidation state increase down the group. This trend is the consequence of inert pair effect due to which two electron of lead in s orbital do not participate in chemical bonding. Hence Pb shows +2 oxidation state predominantly.Whereas no such effect occur in Sn and hence it prefer to form SnCl4\xa0in comparison of SnCl2.\xa0
