JEE Advanced: Group 14
Carbon Family Reactions & Structures for chemca.in
Inert Pair Effect
Stability of +2 state increases down the group: Ge < Sn < Pb.
Consequently, Pb4+ is a powerful oxidizing agent, while Sn2+ is a strong reducing agent.
Silicate Structures
Orthosilicates: Discrete SiO44- units (No shared oxygens).
Pyrosilicates: Two units share one oxygen (Si2O76-).
Sheet Silicates: Three oxygens shared per tetrahedron.
