Intermolecular Forces
Created @January 20, 2025 7:48 PM
Class Pharmaceutical Chemistry
Dispersion/London Dispersion Forces
Attraction from constant movement of electron clouds, a temporary
imbalanced charge leads to weak interaction between particles
Molecule shape can contribute to the significance of dispersion forces
More molecules means more interactions, leads to higher boiling point. More
intermolecular forces present
Dipolar Forces (Dipole Dipole)
Attractions between ends of molecules that are oppositely charged
Hydrogen Bonds
Attraction between lone pair electrons N/O/F and H atom
Requirements
Electron- deficient H atom is attracted to an electron pair
Very electronegative atom w/ electron pair interacts with electron-
deficient H atom
Intermolecular H bonding
Occurs between separate molecules inside a substance
Intermolecular Forces 1
