About 95 % of the eath's crust is composed of silicated minerals, aluminosilicate clays, or silica. The majority of silicate minerals are very insoluble, because they have an infinite ionic structure and because of the great strength of the `Si - O` bond. the basic structural units of silicate is `(sIO_(4))^(4-)` tetrahedra. The `(SiO_(4))^(4-)` tetrahedral may polymerize in to large units by sharing atoms
Which of the following statement is incorrect ?

Options

A. Silicates are wide spread in the earth crust because they are very insoluble in water
B. The `Si - O`, bonds are weaker than `C - O` bonds because of bigger size of silicon atom
C. Zeolites are used as ion exchange matericals, and as molecular sieve
D. Sharing of all four corners of a `SiO_(4)` tetrahedron results in a three dimensional lattice of formula `SiO_(2)`

Answer

B
