Study Notes
Intramolecular Forces
- Hold atoms together within a molecule
- Also known as chemical bonds
Intermolecular Forces
- Attractive and repulsive forces that hold molecules together in a substance
- Types include ion-ion, dipole-dipole, hydrogen bond, and dispersion forces
Ion-Ion Forces
- Occur between ionic compounds
- Exist between oppositely charged ions
- Strength of attraction: HIGH
- Like charges repell each other, opposite charges attract
Dipole-Dipole Forces
- Occur between polar molecules
- Strength of attraction: MEDIUM
- Average dipole-dipole interaction is relatively weak and effective over a very short range
Hydrogen Bond
- Special dipole-dipole force
- Occurs between polar molecules containing H and highly electronegative elements (F, O, N)
- Strength of attraction: MEDIUM-HIGH
Dispersion Forces (London Forces)
- Present in ALL molecules
- Occur between nonpolar molecules
- Strength of attraction: LOW
