Question

The main reason the \(\mathrm{SiCl}_{4}\) is easily hydrolysed as compared to \(\mathrm{CCl}_{4}\) is that
(A) \(\mathrm{Si}-\mathrm{Cl}\) bond is weaker than \(\mathrm{C}-\mathrm{Cl}\) bond
(B) \(\mathrm{SiCl}_{4}\) can form hydrogen bonds
(C) \(\mathrm{SiCl}_{4}\) is covalent
(D) Si can extend its coordination number beyond four

Answer 1

Ans : (D)

Si can extend coordination number as it has vacant 3d orbital
