Chapter 9 Chemical Bonding I: PART 2

Chapter 9 Chemical Bonding I: PART 2. Ionic Bonding Model vs. Reality. Lewis theory: attractions btwn ions are strong ionic compounds should have high MPs & BPs (breaking down crystal should require lots of E ) stronger attraction (larger lattice E), higher the MP.

INTER MOLECULAR FORCES (bonds)

INTER MOLECULAR FORCES (bonds). Occur between molecules Weaker than intra molecular forces. Hydrogen Bonding . One molecule is polar and has a hydrogen in a H-F, H-O, or H-N bond Other molecule has unshared pairs of electrons, usually on F, O, or N F, N, and O are highly electronegative!!!!
