Q. Name the type of the structure of silicate in which one oxygen atom of [SiO₄]⁴⁻ is shared?
A) Three dimensional
B) Linear chain silicate
C) Sheet silicate
D) Pyrosilicate
Explanation
[Solution from source] Sharing one oxygen atom between two SiO₄⁴⁻ tetrahedra gives the Si₂O₇⁶⁻ unit, the pyrosilicate. Chains need two shared oxygens per tetrahedron, sheets three and three-dimensional networks all four. Answer (4).
