Hi there.
00:04
This question is asking about intermolecular forces.
00:08
In other words, forces between molecules that hold them together.
00:13
And there are three basic types of intermolecular forces.
00:16
There are dispersion forces.
00:19
They are the weakest, often called london dispersion forces.
00:25
Let me go ahead and put that in there, since that's the way your question has it.
00:30
So london dispersion forces, they are the weakest.
00:33
They are found in all molecules, but non -polarion.
00:38
Molecules only have london dispersion forces.
00:42
So they would be the only forces in non -polar molecules.
00:47
That's the only time that they would be considered the strongest intermolecular force is in non -polar molecules.
00:54
Then there are dipole dipole forces.
01:00
These are stronger than london dispersion forces and they occur between two polar molecules.
01:14
The strongest of the intermolecular forces are hydrogen bonds...
