Intermolecular forces
can someone give a definition for london forces? the definition in my notes is a bit confusing. Also, is van der waals just a term to describe all intermolecular forces?
Re: Intermolecular forces
According to the textbook, a London interaction is the interaction between instantaneous electric dipoles on neighboring molecules. Van der Waals interactions are Intermolecular interactions that depend on the inverse sixth power of the separation.

Re: Intermolecular forces
van der waals and london forces are terms that are typically used interchangeably.

Re: Intermolecular forces
Van der Waals and London forces are used as the same term. For the definition of London forces, it is essentially the weakest type of intermolecular forces, and this is usually between two dipoles. They are also known as induced dipole- induced dipole interactions as well.

Re: Intermolecular forces
Van der Waals and London interactions are used interchangeably, and refer to induced-dipole induced-dipole interactions. They are the weakest intermolecular force.

Re: Intermolecular forces
Most molecules have London forces, which occur between two dipoles, and are the weakest intermolecular forces relative to the others.
Re: Intermolecular forces
Both London forces and Van Der Waals interactions are the same thing and can replace each other in a a sentence. These are the weakest intermolecular forces compared to the others.

Re: Intermolecular forces
You might also here London forces referred to as induced-dipole-induced-dipole interactions.
Re: Intermolecular forces
Van der Waals bonds are the weakest of the IMF as it depends on the position of the electron. It's weak because the electron are constantly moving, creating temporary dipoles.

Re: Intermolecular forces
can anyone explain why professor Lavelle preferred to London dispersion force to be called Induced Dipole- Induced Dipole?

Re: Intermolecular forces
On the exams do we need to use those terms (induced dipole) or should we just say London Forces?
