Pbcl 4 is less stable than pbcl2

Answer 1

Answer 2

Answer:

Explanation:

As Pb belongs to 4th Group it shows variable oxidation states that are +2 and +4

It's Electronic Configuration is ns²np²

When we move down the group we find that lower oxidation state is more stable than higher one due to inert pair effect so in case of Pb due to the inert pair effect +4 oxidation state of Pb is less stable than +2 state of Pb

So to gain more stability Pb ( +4 ) gains 2 more electrons to become Pb ( +4 ) which is more stable .
