Here we have a series of statements for which we need to classify as true or faults.
00:08
The first statement is lithium fluoride, which is an ionic compound, will have a higher vapor pressure than h2s.
00:20
If it has a higher vapor pressure, then that means it has weaker intermolecular forces.
00:26
Well, an ionic compound is going to have the strongest forces holding the atoms together.
00:32
So this statement is false.
00:35
The next one is hf will have a lower vapor pressure than hbr.
00:42
If it is to have a lower vapor pressure, then it needs to have stronger intermolecular forces.
00:51
So does hf have stronger intermolecular forces than hbr? yes, it does.
00:58
Because hf has hydrogen bonding, while hbr has dipole -dipole, and hydrogen bonding is stronger than dipole -dipole.

Part c.
01:12
Cl2 will have a higher boiling point than ar.
01:16
If it has a higher boiling point, then that means it has stronger intermolecular forces, holding the cl2s closer to each other...
