Key: 17. What type of intermolecular forces does propane (the 3-carbon alkane) experience with other propane molecules? These forces are ________ than those for methane with other methane molecules. a. London dispersion forces, larger b. hydrogen bonding, smaller c. dipole forces, larger d. London dispersion forces, smaller e. hydrogen bonding, larger f. dipole forces, smaller To answer this problem you need to know what an alkane is: a saturated hydrocarbon, that is, a molecular compound containing only carbon and hydrogen bonded by single covalent bonds. So propane has the carbon structure C-C-C, with Hydrogen atoms completing the octet rule for each

Unformatted text preview: carbon. Hydrocarbons like propane are nonpolar and thus experience only London dispersion forces with each other. Compare that to methane, which is just CH 4 . As the size of molecules increases, so do the number of electrons in the molecule. In large molecules like propane, the electrons can slosh around further and it is easier to create small dipoles, so big molecules like propane have bigger London dispersion forces than small molecules like methane....
