Second Lecture
The second lecture had me all confused. Resonance and shapes of molecules and electron geometry. Man that was some pretty confusing stuff I'll tell yah! It took me awhile to get but I finally understood it. The shape is just how many bonded entities there are and pay attention to lone pairs. The electron geometry is just where the electrons are found. If you have two bonds and two electron lone pairs the electron geometry is tetrahedral. It took me a bit to piece it all together but I finally got the click and everything came together! Also the online practice tests helped out a lot in helping me understand all of the things we learned. Resonance tripped me up the most though. When we added polar and nonpolar it frazzled my brain as well! No lone pairs=nonpolar. Nonpolar is symmetrical. Polar is just the unsymmetrical shapes with lone pairs. Only polar shapes are trigonal pyramidal and bent molecules.
