Hi there.
00:04
This question is about forces that we see within molecules and between molecules.
00:10
So let's summarize these first of all and what they are.
00:15
First, i want to look at intermolecular forces.
00:24
What this means are forces between molecules.
00:39
In other words, holding two molecules together.
00:53
These are very important because this is how molecular substances can form liquids or solids.
00:58
Some examples of intermolecular forces include hydrogen bonding, dipole -dipole interactions, and london dispersion forces.
01:24
Sometimes just called london forces, sometimes just called dispersion forces, but they all mean the same thing because they are london dispersion forces.
01:36
Okay, the other thing we could have are intramolecular forces.
01:45
Intramolecular forces refer to the forces within a molecule holding the atoms together to form the molecule.
02:08
In other words, bonds.
02:21
Okay, so we are ready to answer this question now...
