Silicones have the general formula :

Which of the following is wrong about silica?

$$SiO_{2}+A\rightarrow X+Y$$ In this reaction 'Y' is one of the global warming gases. 'A' is the water soluble alkali metal carbonate. Whose molecular weight is 106. The common name of 'X' is :

Hydrolysis of $$SiCl_{4}$$ gives compound $$X$$ and $$HCl$$. On heating to $$1000^{\circ}$$ $$C$$. $$X$$ loses water and forms $$Y$$. Identify $$X$$ and $$Y$$ respectively.

Which of the following Si biocompatible

Which of the following bonds is present in silicone ?

Silica reacts with a hydride of superhalogen to form 'X'. On hydrolysis of 'X', another compound 'Y' is formed. 'Y' on heating at 1000$$^0$$C loses water to form 'Z'. The 'Z' can also be prepared by the reaction

The high melting point of $$ SiO_{2}$$ is due to:

A. $$CCl_{4}$$ does not act as lewis acid. 
B. Silanes are strong reducing agents.
C. Crystalline silica will have Diamond like structure.
Which of the above statement(s) is/are true?

List -I                                                  List -2
Arrange properly.
A. Diamond                                       1.  Metal electrode
B. Graphite                                        2. sp hybridized
C. Silica                                             3. Acheson's process
D. $$CO_2 $$                                             4. Agate
                                                          5. Cutting of glass
The correct match is?
