Which of the following statements about intermolecular forces is incorrect? O Intermolecular forces describe the attractions between two or more separate molecules. O The only intermolecular forces between nonpolar molecules are London forces. Dipole-dipole attractions occur between polar molecules. O Hydrogen bonds are a special kind of covalent bond.

Indicate whether or not each of the following statements about intermolecular forces is true or false. a. Hydrogen bonds are extra strong London forces. b. A London force is a very weak permanent dipoledipole interaction. c. The strength of dipoledipole interactions increases as molecular polarity increases. d.

What are intermolecular forces? How do they differ from intramolecular forces? What are dipole-dipole forces? How do typical dipole-dipole forces differ from hydrogen bonding interactions? In what ways are they similar? What are London dispersion forces? How do typical London dispersion forces differ from dipole-dipole forces? In what ways are they similar? Describe the relationship between molecular size and strength of London dispersion forces. Place the major types of intermolecular forces in order of increasing strength. Is there some overlap? That is, can the strongest London dispersion forces be greater than some dipole-dipole forces? Give an example of such an instance.
