PbX 2 is more...

Question

PbX₂is more stable than PbX₄. Why?

Open in App

Solution

In pbx2 , oxidation state of pb =+2
and pbx4 , oxidation state of pb =+4
we know ,
oxidation state of +2 is more stable than +4 . due to inert pair effect .
this is due to poor screening effect of d and f electrons that restrict ns electron to take part in the bond formation .
so, PbX2 is more stable than PbX4.
