What is the product when chlorine gas is passed over element silicon in powdered state and heated it produce colorless liquid having the formula?
Correct answer: B. SiCl4
- A. SiCl2
- B. SiCl4
- C. Si2CI3
- D. SiCl
Explanation
When chlorine gas is passed over powdered silicon and heated, it produces silicon tetrachloride (SiCl4), which is a colourless liquid.The balanced chemical equation for this reaction is:Si(s) + 2C12(g) → SiCl4(1)Therefore, the formula of the colourless liquid produced is SiCl4, which is silicon tetrachloride. Thus, the correct answer is option B: SiCl4.
