9. Which intermolecular forces are found in CO2? A) dispersion forces and dipole-dipole forces B) hydrogen bonding C) dipole-dipole forces D) dispersion forces E) none of the above
Given the following intermolecular attractive forces 1. Hydrogen bonding 2 Dipole-Dipole 3 London dispersion 4 Ion-dipole When sodium chloride dissolves in water what new attractive forces are formed between solute and solvent?
My answers: Not sure if they are correct. 1. a. London dispersion b. H-bonding, dipole-dipole, london dispersion c. London dispersion d. Ionic, london disperson 2. The second one because not a lot of H+ and less acidic. Need help understanding the meaning of the question. 3. Diethyl cannot h-bond because it does not provide intermolecular bonding engery while 1-b. can form h-bond making strong intermolecular bonds to take up greater engery to break molecules. 4. Not sure...

Order the three types of intermolecular forces: dipole-dipole, London force, hydrogen bonds in terms of strength from weakest to strongest. Give a brief description of each of the different intermolecular forces. Question 24 (6 points) The boiling points for H2O (BP = 100°C) and HS (BP-60°C) are drastically different despite oxygen and sulfur being next to each other on the periodic table. Explain these differences in boiling points utilizing your labels of intermolecular forces and the relative strength of the...
