Ask Question

Why is pbcl4 is less stable than sncl4

Posted by Kartik Rana 6 years, 10 months ago

CBSE > Class 11 > Chemistry

1 answers

Gaurav Seth 6 years, 10 months ago

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 in comparison of SnCl₂.
