What are the Strongest Intermolecular Forces in these Compounds?

Click For Summary
SUMMARY

The discussion focuses on identifying the strongest intermolecular forces present in various compounds, specifically compounds I to VII. The strongest interactions identified include hydrogen bonds in liquid H2O, metal bonds in solid Fe, and ion-dipole interactions in liquid KCN. The participants also explore the nature of bonds in HBr and HI, questioning whether they exhibit ion-ion or dispersion forces. Understanding electronegativity differences is emphasized as a key factor in determining bond types.

PREREQUISITES
  • Understanding of intermolecular forces, including hydrogen bonds and ion-dipole interactions.
  • Knowledge of bond types: ionic, covalent, and metallic bonds.
  • Familiarity with electronegativity and its role in bond formation.
  • Basic chemistry concepts related to molecular structures and states of matter.
NEXT STEPS
  • Research the properties and examples of hydrogen bonds in various compounds.
  • Study the characteristics of ion-dipole interactions and their significance in solutions.
  • Explore the concept of electronegativity and how it influences bond types and strengths.
  • Learn about the differences between ionic, covalent, and metallic bonds in detail.
USEFUL FOR

Chemistry students, educators, and professionals interested in molecular interactions and bonding theories will benefit from this discussion.

For the compounds I to VII pick the letter that corresponds to the correct interactions between particles of that particular compound.
If more than one type of interaction exists for a compound, pick the letter that corresponds to the strongest interaction.


a) Ion-Ion b) Ion-Dipole c) Dipole-Dipole
d) Hydrogen bonds e) Dipole-Induced Dipole f) Dispersion forces
g) Metal bonds h) Covalent bonds







I. liquid BF3 II. solid HBr III. solid Fe



IV. graphite V. liquid H2O



VI. solid HI VII. liquid KCN



all i know is H20 is hydrogen bonds, please help with this!

Which compounds consist of ionic bonds, and which consist of covalent bonds ?

And the one that is a "metal bond" should be pretty easy...
 
yeah Fe is the metal bonds, but HBr and HI could be either ion ion or dispersion?? And the rest I have no clue
 
Have you done electronegativity yet? If so, what is the electronegative difference between two elements under consideration? What does that tell you about the bonds they would form?
