SiCl 4 on hydrolysis forms 'X' and HCl. Compound 'X' loses water at 1000 o C and gives 'Y'. Compounds 'X' and 'Y' respectively are
Options
- AH 2 SiCl 6 , SiO 2
- BH 4 SiO 4 , Si
- CSiO 2 , Si
- DH 4 SiO 4 , SiO 2
Correct answer
D. H 4 SiO 4 , SiO 2
Step-by-step solution
SiCl 4 + 4 H 2 O → H 4 SiO 4 ( X ) + 4HCl H 4 SiO 4 → 1000 o C Δ SiO 2 ( Y ) + 2 H 2 O
