CHEM 101 Lecture Notes - Electric Dipole Moment, Electronegativity
Document Summary
Some more chemical principles; bonding and shapes of molecules (important factor in molecular interactions). Chromatography, process for the separation of component of a mixture based on the relative affinities of the components for two phases, one of which moves relative to the other. Often depends in the polarity of the molecules involved. The extent to which charge is separated in bonds and the shape of the molecule. Chemists visualize electrons as a cloud of negative charge that can be distributed between atoms according to the relative electronegativities. The oscillating electric dipole can interact with an external field such as the electrical part of a light beam and extract energy from it by a process of resonance. The frequencies are in the ir region of the spectrum. A link between atoms that results in a system with lower energy than the separated atoms or ion. Ionic: electron relocated/transferred from one atom to another.
