Question

Inert pair effect is maximum in:

RankGuru · Accepted Answer

The **Inert Pair Effect** refers to the reluctance of the outermost $s$-orbital electrons to participate in bonding in heavy $p$-block elements.
- It results in the preference for an oxidation state that is **2 units less** than the group valency.
- It is most pronounced in **Group 13** ($B, Al, Ga, In, Tl$).
- For **Thallium ($Tl$)**, the $+1$ oxidation state is much more stable than the $+3$ state due to this effect.
