It is because of inability of ns2 electrons of the valence shell to participate in bonding that
A. Sn2+ is oxidising while Pb4+ is reducing
B. Sn2+ and Pb2+ are both oxidising and reducing
C. Sn4+ is reducing while Pb4+ is oxidising
D. Sn2+ is reducing while Pb4+ is oxidising
Answer:D
It is because of inability of ns2 electrons of the valence shell to participate in bonding that
A. Sn2+ is oxidising while Pb4+ is reducing B. Sn2+ and Pb2+ are both oxidising and reducing C. Sn4+ is reducing while Pb4+ is oxidising D. Sn2+ is reducing while Pb4+ is oxidising
Explanation:- Inability of ns2 electrons of the valence shell to participate in bonding on moving down the group in heavier p-block elements is called inert pair effect.
