The main reason that SiCl₄ is easily hydrolyzed as compared to CCl₄ is that (Kerala CEE 2009)
A.Si—Si bond is weaker.
B.SiCl₄ can form hydrogen bonds.
C.SiCl₄ is covalent.
D.Si can extend its coordination number beyond four.✓ Correct
Explanation
It is easily hydrolysed as compared to because in case of vacant d-orbitals are present, so Si can expand its valency but carbon does not have a vacant d-orbitals. Carbon can’t expand its valency. Hence, the correct option is (d).
