Show Answer
Answer:
Correct Answer: B
Solution:
Silicon tetra fluoride on hydrolysis furnishes ortho silicic acid and hydrogen silicofluoride. $ \underset{\begin{smallmatrix} (\text{Silicon tetra} \\ Fluoride) \end{smallmatrix}}{\mathop{3SiF_4}}+\underset{\text{(Water)}}{\mathop{4H_2O}}\xrightarrow{{}}\underset{\begin{smallmatrix} (Ortho \\ \text{Silicic acid}) \end{smallmatrix}}{\mathop{H_2SiO_4}}+\underset{\begin{smallmatrix} (\text{Hydrogen Silico} \\ Fluoride) \end{smallmatrix}}{\mathop{2H_2SiF_4}} $
