MCQ
Name of the structure of silicates in which three oxygen atoms of $[SiO4]^{4-}$ are shared is
- APyrosilicate
- BThree dimensional silicate
- CLinear chain silicate
- ✓Sheet silicate
✓
Answer
Correct option: D.
Sheet silicate
d
In sheet silicates, three out of four oxygen of $S i O_{4}^{4-}$ 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.
