Which one react most violently with cold water
Correct answer: C. SiCl₄
- A. PbCl₄
- B. CCl₄
- C. SiCl₄
- D. GeCl₄
Explanation
Among the options provided, SiCl₄ reacts most violently with cold water. When SiCl₄ comes into contact with water, it rapidly hydrolyzes to produce silicic acid (H₄SiO₄) and hydrochloric acid (HCl), releasing a significant amount of heat in the process. This reaction is more vigorous compared to the other compounds listed. PbCl₄ is stable and does not react violently with water, CCl₄ is inert, and while GeCl₄ does react with water, it is not as reactive as SiCl₄.
