Can anyone explain?
(3) due to inert pair effect
What's the ans @Supreeta_Sen
@arush_kumar_singh 3 is given. But how can it be because of inert pair effect? I'm not convinced. Can you explain?
Could be related by hydration enthalpy.... @Supreeta_Sen
Due to inert pair effect TL,PB,BI are more stable in lower oxidation state.
