Question

The main reason that $SiC{l}_4$ is easily hydrolysed as compared to $CC{l}_4$ is that __________.

• A. Si-Cl bond is weaker than C-Cl bond
• B. $SiC{l}_4$ can form hydrogen bonds
• C. $SiC{l}_4$ is covalent
• D. Si can extend its coordination number beyond four

Answer 1

Answer: (D)

Si can extend its coordination number beyond four

In $SiC{l}_4$ vacant d-orbitals are present. So hydrolysed by co-ordination bond formation and Si expand its valency.
