Question

The main reason that SiCl₄ is easily hydrolysed as compared to CCl₄ is that 

(A) Si-Cl bond is weaker than C-Cl bond. 

(B) SiCl₄ can form hydrogen bonds. 

(C) SiCl₄ is covalent. 

(D) Si can extend its coordination number beyond four.

Answer 1

The correct option (D) Si can extend its coordination number beyond four.   

Explanation:

In SiCl₄ vacant d–orbitals are present. So hydrolysed by co–ordination bond formation and Si expand its valency.
