MCQ
Silicate having one monovalent corner oxygen atom in each tetrahedron unit is
- ✓sheet silicate
- Bcyclic silicate
- Csingle chain silicate
- Ddouble chain silicate
✓
Answer
Correct option: A.
sheet silicate
a
The general formula of Sheet or Phyllo silicates is $\left(\mathrm{Si}_{2} \mathrm{O}_{5}\right) \mathrm{n}^{2 \mathrm{n}-}$. Each $\mathrm{SiO}_{4}$ 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 $\mathrm{A}$
