MCQ
Silicate having one monovalent comer oxygen atom in each tetrahedron unit is
  • sheet silicate
  • B
    cyclic silicate
  • C
    single chain silicate
  • D
    double chain silicate

Answer

Correct option: A.
sheet silicate
a
The general formula of Sheet or Phyllo silicates is $\left( Si _2 O _5\right) n ^{2 n-}$. Each $SiO _4$ tetrahedron shares three oxygen atoms with others and thus by forming twodimensional sheets. These silicates can be cleaved easily just like graphite.
