GenChem 2 L2: Intermolecular Forces of Attraction (2) Flashcards
How to determine which IMF a substance has:
Hydrogen bonded to F,O,N
Hydrogen Bonding
provides the hydrogen atom participating in a hydrogen bond.
hydrogen bond donor
contains the lone pair-bearing electronegative atom
Hydrogen Bond Acceptor
Types of Intermolecular Forces:
are the weakest type of IMFA and are present in between all electrically neutral molecules ― polar and nonpolar molecules
London Dispersion Forces
distortion of electron cloud
Polarizability
non polar atom becomes polar due to the presence of an ion or dipole.
Induced Dipoles
Predicting Intermolecular Forces of Attraction for Molecules
atoms bonded by ionic bonds
Ionic Compounds
Predicting Intermolecular Forces of Attraction for Molecules
transfer of an electron from a metal to nonmetal
Ionic Bonds
Predicting Intermolecular Forces of Attraction for Molecules
the strength of the ion-ion interaction
Coulombs Law
Predicting Intermolecular Forces of Attraction for Molecules
polar or nonpolar covalent molecules
Covalent Compounds
