Question
Select the correct statement(s)
Options
A.Double chain silicates are known as amphiboles.
B.In cyclic silicates two oxygen atoms per tetrahedron are shared.
C.Orthosilicates contain discrete (SiO4)4- units.
D.Asbestos mineral is a double chain silicate and mica is a sheet silicate.
Solution
(A) 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.
(B) If two oxygen atoms per tetrahedron are shared to form closed rings such that the structure with general formula (SiO32-)n or (SiO3)n2n- is obtained, the silicates containing these anions are called cyclic silicates.
(C) Orthosilicates contain discrete [SiO4]4- units i.e., there is no sharing of corners with one another.
(D) The asbestos mineral is a well known example of double chain silicates. The anions of double chain silicates have general formula (Si4O11)n6n- .
