Among the following, the element which show significant inert-pair effect are :
Options:(select one or more)
Answer:
A, C
Solution:
The inert pair effect is significant in heavier p-block elements due to the poor participation of the ns² electron pair in bonding.
It increases down the group because of higher atomic size and shielding effect.
Bi (Group 15) shows strong inert pair effect → +3 oxidation state is more stable than +5.
Pb (Group 14) shows strong inert pair effect → +2 oxidation state is more stable than +4.
Sn shows a comparatively weaker inert pair effect, while C does not show it significantly.
Correct Answer: (A) Bi and (C) Pb
