Document Summary
Chapter eleven: why are intermolecular forces important? a) Intermolecular forces: the attractive forces that exist among the particles that compose matter: lowest surface area : volume ratio = max imf interaction, properties of gases, low density, inde nite shape c) How can we predict the magnitude of the dispersion force for closely related elements or compounds: dispersion force: the imf present in all molecules & atoms i) ii) iii) The result of uctuations in the electron distribution within molecules or atoms. How can we predict the presence of dipole-dipole forces in a compound: dipole-dipole force: exists in all polar molecules i) ii) Because polar molecules have electron-rich and electron-de cient regions, which give them a permanent dipole. How can we predict the presence of hydrogen bonding in a compound: hydrogen bonding: the imf found in polar molecules that contain h atoms bonded directly to f, o, or n i)
