The compound which can be hydrolyzed by means of water is:
Correct answer: B. SiCl4
- A. CCI4
- B. SiCl4
- C. CH4
- D. None of the above
Explanation
Silicon can be hydrolysed by water because the silicon atom of silicon tetrachloride has energetically suitable vacant d-orbitals. Thus, it can accept a lone pair of electrons from the oxygen atom of a water molecule. Therefore, a silicon atom can expand its coordination number beyond four. Due to this reason SiCl4 is hydrolysed.Silicon tetrachloride (SiCl4) can undergo hydrolysis reaction with water to form orthosilicic acid (H4SiO4) and hydrogen chloride (HCl) gas.SiCl4 + 4H2O → H4SiO4 + 4HCl
