Question

Which type of silicate is shown in the figure?

• A. Orthosilicate
• B. Pyrosillicate
• C. Meta silicate
• D. None of these

Answer 1

The correct option is D None of these

When two oxygen of each $Si{O}_4^{4-}$ tetrahedron are shared with others, cyclic or ring structures are obtained. These silicates are known as cyclosolicates or cyclic silicates.
${\left[{Si}_6{O}_{18}\right]}^{12-}$ is an example of cyclosilicate. In this silicate six $Si{O}_4$ tetrahendra linked together.
