Tetrachloride of which element doesn't react with water
Correct answer: A. Carbon
- A. Carbon
- B. Silicon
- C. Tin
- D. Lead
Explanation
The correct answer is Carbon. Carbon tetrachloride (CCl4) is known for its lack of reactivity with water because it is non-polar and lacks lone pairs of electrons that could participate in hydrolysis. In contrast, Silicon, Tin, and Lead tetrachlorides can react with water. Silicon tetrachloride reacts to form silicic acid and hydrochloric acid, due to silicon's affinity for oxygen. Tin tetrachloride forms tin dioxide and hydrochloric acid, and Lead tetrachloride hydrolyzes to give lead dioxide and hydrochloric acid due to the stability of their oxide forms and the presence of available d-orbitals for bond formation.
