Document Summary

Lecture 1: gases are, one of the phases of matter. Lecture 3: states of matter compared, solid. Intermolecular forces: the attractions between molecules are not nearly as strong as the intramolecular attractions that hold compounds together. There are, however, strong enough to control physical properties such as boiling and melting points, vapor pressures and viscosities: four types. London dispersion forces: dipole-dipole interactions, hydrogen bonding. Therefore, the strength of the dispersion forces increases: polarizability of the electrons, volume of the electron cloud. Lecture 4: hydrogen bonding: a dipole-dipole interaction. Chapter 12 continued: the dipole-dipole interactions experienced when h is bonded to n, o, or f are unusally strong. It is related to the ease with which molecules can move past each other: capillary action. Is the ability of a liquid to flow up a thin tube against the influence of gravity.
