GENERAL TYPE OF INTERMOLECULAR

FORCE

DESPERSION FORCEION - DIPOLE FORCE

DESPERSION FORCE

Also known as Loudon Despersion Force (LDF) instataneous dipole, induced dipole

Type of force acting between atoms and molecules

LDF is the weakest intermolecular force

FRITZ LONDON A Jewish physicist

and professor, his fundamental contribution of Thesis in Chemical Bonding and Intermolecular force (LFD)

Do all molecules have DESPERSION FORCES?

The more forces that catch together, the more forces (LDF) that we can find.

NOTE:

ION – DIPOLE FORCE

Attraction between ionic and polar molecules

These ion-dipole force are much weaker than the covalent or ionic bonds.

An ion-dipole forces is an attractive force that results from the electrostatic attraction between an ion and a neutral molecule that has a dipole.

Identifying the type of forces as a reflected by the properties of substances.
