Question

In $\mathrm { SiO } _ { 4 } ^ { 4 - }$ , the tetrahedral molecule, two oxygen atoms are shared in.

A

Sheet silicates

B

Double – chain silicates

C

Chain silicates

D

Theree – dimensional silicates.

Answer

Chain silicates

Explanation

Solution

: In sheet silicates, three oxygen atoms of each tetrahedral are shared with adjacent $\mathrm { SiO } _ { 4 } ^ { 4 - }$ tetrahedral. In chain silicates, two oxygen atoms are shared by each tetrahedral.

Double – chain silicates occur when tetrahedral form a double chain by sharing two or three oxygen atoms. In 3D silicates, each tetrahedral shares all the four oxygen atoms with its neighbours.
