The stability of ions of Ge Sn and Pb wi...

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+)`

Text Solution

Verified by Experts

The correct Answer is:
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+)` .
