Types of Intermolecular Forces Flashcards
It exists between polar molecules.
Dipole-dipole forces
What is the force acting on dipole-dipole forces?
Van Der Waals Force
Dipole-dipole forces is much ___ than ionic or covalent bonds.
Weaker
READ ONLY
Since the opposite attracts, dipole-dipole forces are the attractive force between the positive end of one polar molecule and the negative end of another polar molecule.
It results from the interaction between ion and a polar molecule.
Ion-dipole forces
Ion-dipole forces results from the ___ attraction.
Electrostatic
It is commonly found in solutions for ionic compounds in polar liquids.
Ion-dipole force
Ion-dipole forces become stronger as the ___ increases or ___ increases.
Charge of ion or magnitude of dipole
In ion-dipole forces, a cation attracts the partially ___ end of a neutral polar molecule and anion attracts the partially ___ end of a neutral polar molecule.
Negative, positive
This type of force exists between all atoms and molecules, and it is the only force acting in nonpolar molecules.
London dispersion forces
It is the weakest intermolecular force.
London dispersion forces
READ ONLY
The london dispersion forces result from temporary dipole moments induced in ordinarily nonpolar molecules, where electrons move around the nucleus and an uneven distribution causes momentary charge separation.
It is the special type of dipole dipole interaction.
Hydrogen bond
It exists only in molecules that contain a hydrogen atom bonded to a highly electronegative atom.
Hydrogen bond
It is the strongest intermolecular force.
Hydrogen bond
