Vapor Pressure question

In Ty Jacob's notes it says...

What affects vapor pressure?
•Vapor pressure decreases with increasing IMF.
•Vapor pressure increases with increasing boiling point.
•Vapor pressure decreases with increasing molar mass.

However, if you have increasing IMFs, doesn't that mean you have increasing boiling point as well? Why would the vapor pressure trends be different for the first 2?

Hmm I believe the second one is off.

Just know this
Higher Intermolecular Forces lead to higher boiling pts, higher melting pts, higher viscosity, higher surface tension, but lower vapor pressure

VP is the odd man out

yep that second one is incorrect. Biotic's comment is useful!

There are errors in his note, Id recommend not using those at all unless it was proofread by someone have solid background in chemistry (just use chad, destroyer, and bootcamp) because those errors can confuse your knowledge big time that can resulted in lower DAT score.
