Question

Please give your own examples of intermolecular forces: The forces that hold condensed states together. Below you will find key questions.

1. Know and understand that intermolecular forces originate from the interactions between charges, partial charges, and temporary charges on molecules, atoms, and ions.

2. Know and understand that dispersion (London) forces result from fluctuations of electron distribution within molecules and atoms.

3. Identify and predict how the shape and sizes of molecules or atoms affect the magnitude of dispersion forces the particles exhibit as well as macroscopic physical properties like a boiling point.

4. Know and understand that polar molecules have permanent dipoles that attract each other through dipole–dipole interactions.

5. Know and understand the phenomenon of hydrogen bonding.

6. Predict the ability of molecules to exhibit hydrogen bonding.

7. Recognize hydrogen bonding as the force that holds double-stranded DNA together.

8. Rank a series of molecular compounds with respect to the boiling point.

9. Know and understand that the interaction of ions and dipoles leads to the dissolution and solvation of ions by water and other polar liquids.
