Types of Attractions
Intramolecular
- WITHIN the molecule
- Ionic, Covalent, Metallic
- Primary Strength
Intermolecular
- BETWEEN molecules
- LDF, Dipole, H-Bond
- Physical Properties
Covalent Naming Rules
Rule 1: Use Prefixes
Identifies atom counts
Rule 2: End in -ide
Example: Oxide, Chloride
Rule 3: First Element
No "mono" on first atom (e.g., CO)
Prefix Key
1: Mono-
6: Hexa-
2: Di-
7: Hepta-
3: Tri-
8: Octa-
4: Tetra-
9: Nona-
5: Penta-
10: Deca-
What is VSEPR?
Valence Shell Electron Pair Repulsion
"Electron domains move as far apart as possible because they repel each other."
Repulsion Determines Geometry
Common Molecular Shapes
Linear
180°
Trigonal
120°
Tetrahedral
109.5°
Bent
<109.5°
Note: Diatomic elements (like H2 or O2) are always Linear.
Polarity & Symmetry
Symmetrical
- Charges cancel out
- Nonpolar
- CH4 O2 CO2
Asymmetrical
- Uneven distribution
- Polar
- H2O NH3 HCl
IMF Hierarchy
Hydrogen Bonding
Strongest
Dipole-Dipole
Medium
London Dispersion
Weakest
Stronger IMF
= Higher Boiling Point
Stronger IMF
= Higher Viscosity
H2O
1 Shape: Bent
2 Symmetry: Asymmetrical
3 Polarity: Polar
4 Dominant IMF: Hydrogen Bond
