Question 71: [Physical > Chemical Bonding]
Silicon tetrachloride, SiCl4, is a liquid of low boiling point. In the presence of water it decomposes
to form silicon(IV) oxide and hydrogen chloride.
What types of bonding occur in SiCl4(I)?
1 co–ordinate bonding 2 covalent bonding 3 van der Waals forces
1 co–ordinate bonding 2 covalent bonding 3 van der Waals forces
Reference: Past Exam Paper -June 2003 Paper 1 Q31
Solution 71:
Answer: C.
Silicon tetrachloride is a molecule with covalent bonds therefore option 2 is true.
There are no coordiante bonds within silicon tetrachloride however as it has a simple molecular structure, VDW forces are present between molecules therefore option 3 is true.
