Intermolecular forces are the forces that hold molecules together (like in liquids and solids), How to Balance Redox Reactions (Acidic Solution), How to Balance Redox Reactions (Basic Solution), van der Waals' Equation for Non-Ideal Gases, Arrhenius vs Bronsted-Lowry vs Lewis Acids, Br2 + Alkene (Adding across a double bond), HCl + Alkene (Adding across a double bond). 1. The strongest intermolecular forces are in ion-ion bonds which happen when a metal bonds to another metal. 2. The next strongest forces are ion-dipole bonds which happen when metals bond to nonmetals. 3. The third strongest force is a type of dipole-dipole force called hydrogen bonding. Negative sign indicates the attractive interaction. The strength of this type of force depends on the size and geometry. Step 3: State the strongest intermolecular forced observed by the molecule. This leads to tightly packed electrons that are less likely to release an electron. London dispersion forces are the dominant intermolecular forces present in non-polar molecules, or molecules that don't have slightly positive and negative sides. Polar bonds involve electronegativity differences between 0.4 to 1.7 and nonpolar bonds involve electronegativity differences less than 0.4 This will identify if the molecule possesses dipole-dipole interactions or hydrogen bonding.
