General Chemistry 2 Exam 1 Study Guide – Intermolecular Forces, Bonding & Polarity|Verified Questions Complete With A+ Graded Rationales Latest Updated 2026 What are the five types of forces 1. ion-ion interactions 2. Ion-Dipole interactions 3. Dipole-Dipole interactions 4. Hydrogen Bonding 5. Dispersion Forces Ionic Bond -A chemical bond that results from the electrostatic attraction between cations and anions. Coulomb's Law -E is proportional to Q₁Q₂/d -Has to do with the strength of Ion-Ion interactions. When is the energy of the interaction big according to Coulomb's Law? -Energy of interaction is big when Q₁Q₂ is large and d is small Which is more important distance or charge in determining strength -Charge trumps size Ion-Dipole interaction An attractive force between an ion and a molecule that has a permanent dipole moment. Dipole Any molecule that is polar Dipole Moment A quantitative expression of the polarity of a molecule. Strength of Ion-Dipole Interaction depends on -Charge, size of ion -How polar the molecule is Ion-Dipole Interaction impacts solubility -Big charge: strong ionic bonds, hard to break solid apart -Big Ion: not as much ion-dipole interaction -Big charge, bid ion tend to be insoluble compounds Dipole-Dipole Interaction -An attractive force between polar molecules Strength of Dipole-Dipole Interaction Strength depends on the size of the dipole moment. What does the dipole moment (dipole-dipole interaction) have to do with boiling point -Higher di
