In `SiO_(4)^(4-)` the tetrahedral molecule two oxygen atoms are shared in

Options

A. Two dimensional silicate
B. Pyrosilicate
C. Three dimenensional silicate
D. linear chain silicate

Answer

A

Explanation

`(1)` In two dimensional sheet silicates, three oxygen atoms of `[SiO_(4)]^(4-)` are shared with adjacent tetrahedral `[SiO_(4)]^(4-)` units.
`(2)` One oxygen atom is shared between two adjacent tetrahedra `,[SiO_(4)]^(4-)`
`(3)` All four oxygen atoms are shared between adjacent tetrahedra, `[SiO_(4)]^(4-)`.
`(4)` Two oxygent atoms are shared between adjacent between tetrahedra, `[SiO_(4)]^(4-)` forming a linear chain.
