van der Waals Forces
Dipole-Dipole Force
Appears Between: Dipoles and Dipoles
Examples:
Sulfur Dioxide (SO2) [BP: -10 C]
Arsine (AsH3) [BP: -62.5 C]
Hydrogen Chloride (HCl) [BP: -85.05 C]
Dipole-Induced Dipole Interaction
Appears Between: Dipoles and Non-polar Molecules
Examples:
Sulfur Dioxide (SO2) and Hydrogen Gas (H2)
Nitrogen Dioxide (NO2) and Helium Gas (He)
Water (H2O) and Carbon Tetrachloride (CCl4)
Dispersion Forces
Appears Between: Non-polar Molecules and Non-polar Molecules
Examples:
Helium (He) [BP: -268.9 C]
Hydrogen (H2) [BP: -252.9 C]
Xenon (Xe) [BP: -108.1]
Ion-Diople Forces
Ion-Dipole Force
Definition: When one pole of a dipole is attracted to an oppositely charged ion. The
negative pole of a dipole will be attracted to a cation (positive charge) and the positive pole
of a dipole will be attracted to an anion (negative charge.)
Appears Between: Ions and Dipoles
Examples:
Water (H2O) and Dissolved Sodium Ion (Na+) in Sodium Chloride (NaCl) Solution
Water (H2O) and Dissolved Chloride Ion (Cl-) in Hydrogen Chloride (HCl) Solution
Water (H2O) and Dissolved Calcium (Ca) in Calcium Hydroxide (Ca(OH)2) Solution
Ion-Induced Dipole Interaction
Definition: When an ion approaches a molecule without a dipole and causes a
change in the distribution of charges to induce a dipole.
Appears Between: Ions and Non-polar Molecules
Examples:
Cesium Fluoride (CsF) [BP: 1231 C]
Lithium Iodide (LiI) [BP: 1676 C]
Cesium Iodide (CsI) [BP: 1280 C]
Hydrogen Bonding
Examples:
Ammonia (NH3) [BP: -33 C]
Water (H2O) [BP: 100 C]
Hydrogen Fluoride (HF) [BP: 19.5 C]
Examples:
Ammonia (NH3) [BP: -33 C]
Water (H2O) [BP: 100 C]
Hydrogen Fluoride (HF) [BP: 19.5 C]
Examples:
Ammonia (NH3) [BP: -33 C]
