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

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
