It is because inability of ns2 electrons of the valence shell to participate in bonding that
1. Sn2+ is reducing while Pb4+ is oxidising agent
2. Sn2+ is oxidising while Pb4+ is reducing agent
3. Sn2+ and Pb2+ are both oxidising and reducing agent
4. Sn4+ is reducing while Pb4+ is oxidising agent
The correct statement among the following is :
1. | Sn2+ is an oxidizing agent while Pb4+ is a reducing agent. |
2. | Sn2+ and Pb2+ both are oxidizing agents. |
3. | Sn4+ is a reducing agent while Pb4+ is an oxidizing agent. |
4. | Sn2+ is a reducing agent while Pb4+ is an oxidizing agent. |
