This chemistry video tutorial provides a basic introduction into london dispersion forces also known van der waals forces. London dispersion forces arises from the electrostatic interactions between temporary dipoles and induced dipoles. A dipole is a polarized particle that contains a separation of charge - one part of the particle is partially positive and the other part is partially positive. Polar molecules contain permanent dipoles. Nonpolar molecules do not usually contain a dipole moment but can become a temporary dipole due to the distortion of the electron cloud. Atoms and molecules with a large number of electrons are highly polarizable, that is, they have a higher probability of turning into a temporary dipole. A dipole can cause another molecule to turn into a temporary dipole. This is known as an induced dipole. The interactions between temporary instantaneous dipoles and induced dipoles are known as van der waals interactions or london dispersion forces. Large molecules have a high amount of london dispersion forces and therefore have higher boiling points than smaller molecules. Boiling point is directly related to the amount of van der waal interactions among molecules.

I would just like to say I appreciate the way you explain things in a direct and easy-to-understand manner, and only wish that University, College, and High School professors and teachers could be even half as good as you. Thank you for helping students everywhere.

I think the temporary polar molecule induces the other molecule due to dipole moment which pushes the electrons in the induced molecule not because the electrons are attracted to the positive charge of the inducing molecule as they should have been more attracted to the positive charge of the induced molecule as it is nearer

the delta symbol with a positive means that one side is slightly positive whereas if it has a negative symbol near it, that side is slightly negative

dipole-dipole because it occurs in polar molecules and water is a polar molecule. therefore molecules with dipole-dipole interaction are more soluble in water

You'd think more surface area allows more heat to be absorbed, but apparently not

@tompickering6626 4 жыл бұрын

It's because intermolecular forces occur on the surface of the atom or molecule, so the larger the surface area the more room for the intermolecular forces meaning a higher melting and boiling point.
