1 Intramolecular forces vs. Intermolecular forces

2 Intramolecular- forces that hold atom together within a molecule
These include: Ionic, Polar and nonpolar covalent, and metallic bonds

3 Metallic bond- occurs between atoms of metals in which valence electrons are free to move; attraction between mobile electrons and fixed positively charged metal ions

4 Strongest to Weakest: Metallic Ionic Polar Covalent Nonpolar Covalent

5 Intermolecular- forces that exist between compound units

6 These include: Dipole-Dipole, Hydrogen bonding, and London Dispersion Forces
Dipole-Dipole forces occur when the partially positive charged region of a molecule is attracted to the partially negative charged region of a molecule

7 Hydrogen bond is a special kind of dipole-dipole interaction between a hydrogen atom bonded to oxygen, nitrogen, or fluorine.

8 London Dispersion forces exist between all types of compounds.

9 Strength: Dipole-Dipole= strong Hydrogen bond= strong London Dispersion= weak

10 Identify the intermolecular forces:
