Name of the structure of silicates in which three oxygen atoms of [SiO4]4− are

Question -

Name of the structure of silicates in which three oxygen atoms of $[S i O_{4}]^{4 -}$ are shared -

Options:

A . Pyrosilicate

B . Sheet silicate

C . Linear chain silicate

D . Three dimensional silcate

Answer: Option B
:
B

(i) In such silicates, three oxygen atoms of each tetrahedra are shared with adjacent $S i O_{4}^{4 -}$ tetrahedra.

(ii) such sharing forms two dimensional sheet structure with general formulae $(S i_{2} O_{5})_{2}^{2 -}$ as shown below
