Question

Which of the following product is formed when $Si{F}_4$ reacts with water?

• A. $Si{F}_3$
• B. $H_{4}Si{O}_4$
• C. $H_{2}S{O}_4$
• D. $H_{2}Si{F}_4$

Answer 1

The correct option is B $H_{4}Si{O}_4$

In reaction with water, $Si{F}_4$ (like $SiC{I}_4$) gets hydrolysed to form $H_{4}Si{O}_4$ (silicic acid).
$Si{F}_4+4H_{2}O⟶Si(OH{)}_4$ or $H_{4}Si{O}_4+4HF$
(Silicic acid)
