Polar Molecules

Basic objective of this lecture is to focus on Polar Molecules. This lecture briefly presented on are molecules that contain polar bonds necessarily polar and determine if a molecule is polar we need to look at the overall direction of polarity. Here also discus to draw in polarity arrows on molecule and determine if the molecules are polar or not. Finally briefly describe on Ionic Bonds, Metallic Bonding, Ionic Crystals, Crystal formation etc.
