Hi there.
00:04
In this question, we are comparing ionic compounds and molecular compounds.
00:12
I want to know how they compare in terms of melting points, boiling points, and ease of vaporization.
00:18
So for this question, ionic compounds, typically, this is not always the case.
00:33
There are certainly exceptions, but ionic compounds typically have much higher boiling points, melting points, and ease of vaporization than molecular compounds.
01:10
Okay, let's look at letter b as to why.
01:14
In order for something to change state, the forces holding the particles together must be broken.
01:21
In ionic compounds, those are the ionic bonds that must be broken.
01:35
In molecular compounds, if we think about what holds molecules together as a solid or a liquid, that would be the intermolecular forces.
02:05
Those intermolecular forces of hydrogen bonds, dipole -dipole interactions, london dispersion forces.
02:21
So generally speaking, the strength of ionic bonds, let's try that again.
02:40
It was, all right, here we go.
02:42
The strength of ionic bonds, generally speaking, are considerably stronger, that might or not be wrong weather, are considerably stronger than i .m.
