Matching Pairs Polarity and IMFOnline version Polarity and Intermolecular Forces by Leslie Sena 1 Dipole-Dipole (D-D) 2 Electron Rich Region 3 Induced Dipole-Induced Dipole (ID-ID) London Dispersion Force (LDF) 4 TeCl2 5 Dipole-Induced Dipole (D-ID) 6 SeF6 7 Polarity 8 Intermolecular Forces 9 Hydrogen bond (H-Bond) 10 Electronegativity 11 Electron Poor Region between two nonpolar molecules between two polar molecules occurs when there is an unequal sharing of electrons Attractive forces between molecules ability of an atom to attract electrons polar Only happens when Hydrogen is bonded with Nitrogen, Oxygen or Fluorine; Strongest IMF the smaller region of a dipole; dipole arrow points away from region between one polar and nonpolar molecule nonpolar the bigger region of a dipole; the dipole arrow points toward region
