SUMMARY

The discussion centers on the covalent bonding characteristics of SiO2 (silicon dioxide) and C6H12O6 (glucose). SiO2 is confirmed to be covalently bonded due to its network structure, while C6H12O6 exhibits both covalent and hydrogen bonding. The participants clarify that hydrogen bonds do not count as covalent bonds, reinforcing that SiO2 is the primary example of a covalently bonded substance in this context. Additionally, the discussion touches on the nature of intermolecular forces in carbon allotropes.

PREREQUISITES
  • Covalent bonding principles
  • Understanding of molecular structures
  • Knowledge of intermolecular forces
  • Familiarity with chemical compounds SiO2 and C6H12O6
NEXT STEPS
  • Research the crystal structure of SiO2 and its implications for covalent bonding
  • Explore the differences between covalent bonds and hydrogen bonds
  • Investigate the properties of carbon allotropes and their bonding types
  • Learn about intermolecular forces such as dipole-dipole and van der Waals interactions
USEFUL FOR

Chemistry students, educators, and professionals interested in molecular bonding, chemical structures, and the properties of substances like SiO2 and C6H12O6.

I tried to google this but i found 2 substances that are covalently bonded. SiO2 and C6H12O6. Which one is the correct one? does hydrogen bonds count as covalent bonds? if not then it might be SiO2... Anyone have any ideas? Thanks

I'm guessing A)

carbon allotropes are held together by intermolecular covalent bonds, intramolecular bonds don't apply.

you'll find that the intermolecular bonds may be dipole-dipole, vander wall etc...despite intramolecular covalent bonding in the other choices
 
I'll go for C.For A i'd the graphite as the typical counterexample.Check the crystalization geometry of [itex]\mbox{SiO}_{2}[/itex],i think it fits.
