- Silicon dioxide (silicon (4 oxide)
- Giant covalent structure
- Macromolecular
- Covalent network
- Strong intramolecular covalent bonds throughout the structure
- Solid with very high mpt.
- Oxidation state of +4
- tetrahedral- 109.5
- Mpt= 1610
- Bpt= 2230
- Si atoms are larger than C atoms as they have more shells, the bigger the atoms the larger the bond.
- This means the bond is too big for a pi bond to form.
- Si does not form double bonds.
- This means the bond is too big for a pi bond to form.
- SiO2 is insoluble in water
- You would have to break the covalent bonds- not enough energy/ forces of attraction
