The basic structural unit and its geometry in silicates is

A) \[Si{{O}_{2}},\] tetrahedral

B) \[SiO_{4}^{4-},\]square planar

C) \[Si{{O}_{2}},\]square planar

D) \[SiO_{4}^{4-},\]tetrahedral

Correct Answer: D

Solution :

Silicates are the compounds with basic unit of \[SiO_{4}^{4-}\]anion. In\[SiO_{4}^{4-}\]each Si atom is linked directly to four oxygen atoms tetrahedrally. tetrahedtstructure of\[SiO_{4}^{4-}\]unit
