Which of the following is correct statement ?

Options

A. Double chain silicates are known as amphiboles.
B. In cyclic silicates two oxygen atoms per tetrahedron are shared.
C. Orthosilicates contain discrete `(SiO_(4))^(4-)` units.
D. All arer correct statements

Answer

D

Explanation

Which of the following…………
(1) The double chain silicates can be drawn in which two simple chains are joined together by shared oxygen. Such compounds are also known as amphiboles.
(2) If two oxygen atoms per tetrahedron are shared to from closed rings such that the structure with general formula `(SiO_(3)^(2-))_(n) or (SiO_(3))_(n)^(2n-)` is obtained, the silicates containing these anions are called cyclic silicates.
(3) Orthosilicates contain discrete `[SiO_(4)]^(4-)` units i.e. there is no sharing of corners with one another.
