Text Solution

Verified by Experts

The correct Answer is:
A-PQRS;B-PQRS;C-PQ;D-PQ
`rarr` All silicates G.F `SiO_(4)^(2)` with tetrahedral shape & `sp^(3)` hybridisation
`rarr` In each `SiO_(2) - SiO_(2)-50%` ionic 50% covalent
`rarr` Cyclic & single chain silicates have `(SiO_(3))_(n)^(-2n)` has general formula & two oxygen atoms are shared by each unit.
