Dipole-Dipole Forces
Attraction between molecules with dipole moments
The larger the difference in electromagnetic, what happens to dipole moment?
increases in size
Inter-molecular Forces
Forces that exist between the molecules/atoms that a substance is composed of
What bonds are INTRAMOLECULAR?
ionic and covalent bonding
Dipole-Dipole forces are considered?
uneven, polar, and weak
Dipole Dipole force interactions maximize what between the atoms?
attractive forces
Dipole Dipole force interactions minimize what between the atoms?
repulsive forces
Dipole dipole forces compared to ionic solids?
1% as strong
Dipole Dipole forces only exist in what phases?
solid and liquid
Hydrogen bonding is what strength?
strong
Hydrogen bonding is a specific example of?
Dipole-Dipole attraction
Hydrogen bonding is only between?
hydrogen and oxygen, fluorine, nitrogen
What gives water its unique properties?
hydrogen bonding
London dispersion forces are considered?
non-polar and most weak
In London dispersion forces what are formed?
instantaneous dipoles
Molecules without dipole moments still need to have?
ability to exert force on one another
instantaneous dipoles exist in?
non-polar molecules and diatomic gases
The random movement of electrons can create?
non-symmetrical electron distribution
Instantaneous dipoles can induce?
short lived dipole in neighboring molecules
London dispersion forces exist between all molecules but are?
the weakest forces of attraction
Polarizability
how easy the electron cloud of an atom can be distorted to give a dipole charge
Polarizability increases with?
the number of electrons in a molecule
the more electrons a molecule has the more chances for?
a momentary dipole interaction to occur
CCl₄ experiences greater London dispersion forces than?
CH₄
