Study Notes
Intermolecular Forces
- Intermolecular forces are forces between molecules (covalent)
- Three types of intermolecular forces exist: London Dispersion, Dipole-dipole, and Hydrogen bonding
London Dispersion Forces
- This force occurs between nonpolar molecules
- Polarity briefly develops in the molecule due to the constant shifting of electrons
- This is a temporary dipole force
Dipole-Dipole Forces
- This force exists between polar molecules
- The positively and negatively charged regions of polar molecules attract each other
- This is a permanent dipole force
Hydrogen Bonding
- This force exists between molecules with hydrogen bonded to a highly electronegative atom (like nitrogen, oxygen, or fluorine)
- This is a strong type of dipole-dipole attraction
Ion-Dipole Forces
- This force occurs between an ion (positive or negative) and a polar molecule
- The ion attracts the oppositely charged region of the polar molecule
