1. REVIEW TIPS FOR BONDING EXAM OF MONDAY 3/7/16 1)IONIC CHARACTER IS A MEASURE OF POLARITY FOR POLAR COVALENT MOLECULES. H-Cl H-I H-F Electronagativity of H= 2.2, I= 2.7, Cl = 3.2, F=4.0 From table S. Ionic Character 3.2 – 2.2 = 1 Ionic Character 2.7 – 2.2 = 0.5 Least polar Ionic Character 2.7 – 4 = 1.3 most polar
