Question

Silicate having one monovalent corner oxygen atom in each tetrahedron unit is:

• A. sheet silicate
• B. cyclic silicate
• C. single chain silicate
• D. double chain silicate

Answer 1

Answer: (A)

sheet silicate

The general formula of Sheet or Phyllo silicates is (Si${}_2$O${}_5$)n${}^{2n-}$. Each SiO${}_4$ tetrahedron shares three oxygen atoms with others and thus by forming two-dimensional sheets. These silicates can be cleaved easily just like graphite.

Hence, the correct option is $\text{A}$
