Ionic molecules has ionic bonds Nonpolar molecules has dispersion (Van del Waals) Polar molecules could either have hydrogen bonding or Dipole-Dipole. Hydrogen bonding is when you have F, O or N with H, every other polar molecule is dipole-dipole.
a. polar- dipole-dipole b. polar- hydrogen bonding c. nonpolar- dispersion d. nonpolar- dispersion e. polar- dipole-dipole f. polar-dipole-dipole g. nonpolar- dispersion h. polar- hydrogen bonding.
