Question

which one of following is more stable in +2 oxidation state

Answer 1

D)Pb

Pb has most stable oxidation state due to inert pair effect. The stability of lower oxidation state increasses on moving down the group.  Hence in Pb group as we mkve down the stability of +2 state goes on becoming more than +4 state due to inert pair effect.
