Study Notes
General Chemistry 2 - Grade 11, Quarter 3, Module 1: Types of Intermolecular Forces
- Intermolecular Forces (IMF): Forces of attraction between molecules. These forces impact physical properties like melting and boiling points.
- Ion-Ion Interaction: Attraction between ions with opposite charges. Strength increases with larger magnitude of charges and decreases with increased distance between ions.
- Ion-Dipole Interaction: Interaction between an ion and a polar molecule (like water). Ions are attracted to the oppositely charged poles of the molecule.
- Dipole-Dipole Interaction: Attraction between polar molecules. The positive end of one molecule is attracted to the negative end of another.
- Hydrogen Bonding: A specific type of dipole-dipole interaction. Occurs when hydrogen is bonded to highly electronegative atoms (N, O, F). It's the strongest IMF type.
- London Dispersion Forces (LDF): Weakest IMF. Temporary dipoles are created due to uneven electron distribution within molecules. Strength increases with larger number of electrons.
