Q. Name the structure of silicates in which three oxygen atoms of $[SiO_4]^{4-}$ are shared is
IIT JEEIIT JEE 2005The p-Block Elements
Solution:
In sheet silicates, three out of four oxygen of $SiO^{4-}_4$ unit are shared as shown below : In pyrosilicates, there is only one shared oxygen, in linear chain silicates, two oxygen per tetrahedra are shared while in three-dimensional silicates, all four oxygens are shared.
