The stability of ions of Ge Sn and `Pb` will be in the order .A. `Ge^(2+) lt Sn^(2+) lt Pb^(2+)`B. `Pb^(2+) gt Pb^(4+)`C. `Sn^(4+) gt Pb^(2+)`D. `Ge^(4+) lt Sn^(4+) lt Pb^(4+)` |

Answer» Correct Answer - A::B Down the group stability of lower oxidation state increases due to inert pair effect `underset("Decreasing stability")overset(Pb^(2+) gt SN^(2+) gt Ge^(2+))rarr` Also `pb^(2+)` is more stable than `Pb^(4+)` . |
