Which one shows most pronounced inert pair effect?

Question

Which one shows most pronounced inert pair effect? (A) Si (B) Sn (C) Pb (D) C

Tardigrade Admin · Accepted Answer

The reluctance of the s-electrons of the valence shell to take part in bonding is called inert pair effect. It increases on moving down in a group Hence, Pb shows most pronounced inert pair effect.
