Question

Which of the follownig has the most stable +2 oxidation state ? a) Sn b)Agc)Fe d)pb

Answer 1

Pb 2 positive is more stable because of the inert pair effect as we go down the group inert pair effect is increases lower Oxidation state is more stable when the size of molecule it large
Pd is the cartoon family element
down the group lower Oxidation state is increasing while higher Oxidation State decreases no that is the reason Pd no that is the reason Pd to positive more stable due to the inert pair effect to positive more stable due to the inert pair effect

Answer 2

$\bold{ans :option \: (d) \: \: \: Pb}$


Lead , Pb is most stable in +2 oxidation state because in Pb atom , poor sheilding effect of d - and f - electrons , that restrict ns electrons to take part in the bond formation.

in simple way, we can say that Pb is stable due to inert pair effect acts on Pb.
