i. `SiCl_4 overset (H_2O) (rarr) (X) overset (100^@C) (rarr)(Y)`
In the above reaction (X) and (Y) respectively are :

A

`SiO_(2)` and `Si`

B

`H_(4)SiO_(4)` and `SiO_(2)`

C

`H_(2)SiCl_(6)` and `SiO_(2)`

D

`H_(2) SiO_(4)` and `Si`

Text Solution

Verified by Experts

i. `SiCl_4 + H_2 O rarrunderset ((Y))( Si (OH)_4 ) + 4 HCl`
`Si (OH)_4 overset (1000^(@)C) (rarr) underset ((Y)) (SiO_2) + 2H_2O`
Hence (X) and (Y) are ` Si(OH)_4` or `H_4 SiO_4` and `SiO_2` . Respectively .
