Document Summary

W, oct 1, 2pm f, oct 3, 8am. Online for marks quiz when we finish lewis structures. Different en shared e are closer to one atom (the more electronegative, say x) than to the other atom (say h). When an electric field is applied the partial charges will align with the opposite charged electrode. The ability of an atom in a molecule to attract e to itself. A scale in which atoms are ranked based on their ability to attract electrons. The larger the number, the stronger the attraction of the electrons by that atom. A bond contains a positive end (pole) and negative end (pole). Nbr3 is trigonal pyramid no dipole cancellation. Bf3 is planar, b f dipoles cancel no net dipole. In h2o no cancellation of dipoles b/c of geometry. Chcl3 all dipoles cancel out non polar dipoles don"t cancel.
