intermolecular forces resulting from the attraction of oppositely charged regions of polar molecules
attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces; these are the weakest interactions between molecules
the mixing of several atomic orbitals to form the same total number of equivalent hybrid orbitals
attractive forces in which a hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom
a bond angle of 109.5 degrees that results when a central atom forms four bonds directed toward the center of a regular tetrahedron
