Compounds with Hydrogen bonds (Hydrogen bonded to N,O or F) will tend to have stronger bonds thus a higher BP, then the compounds with a stronger polarity determine bond strength, and finally dispersion forces (Molecular mass)
So in conclusion if you have
ex.
HF and CO2
HF has a higher BP because it has a stronger bond than CO2 (it has a hydrogen bond, while CO2's strongest bond is a polar bond)

∙ 13y agoThe boiling points for most molecules can be found online.
But the best way to figure out which molecule has a higher boiling point is to boil (or condense for gasses) them. If that's not an option, it's best to look at the polarity of the molecule. Molecules with poles (like water) will have higher boiling points because there is a stronger attraction between oppositely polar ends of molecules within the substance. The best example of these intermolecular forces is the hydrogen bond which involves the attraction of hydrogen in a molecule to the (-) polar atom in another molecule ( IE water).

Boiling point of polar molecule?
The boiling point is specific for each substance.
Why is the boiling point of water higher than the boiling point of argon?
Argon is a monoatomic gas, held by weak van der Waals forces of attraction. Water is a polar covalent molecule held together by stronger hydrogen bonds and hence have higher boiling point than argon
Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
Why n-pentane has higher melting point than neopentane?
It is because n-pentane is a straight chain hydrocarbon meaning it has more surface area to reach the boiling point, neopentane has significantly less surface area that's why it will boil quicker than n-pentane. The more branched molecule, the lower is its boiling point will be & the less branched molecule, the higher its boiling point will be. For combustion energy the opposite holds true, the more branched molecule has a higher energy than an unbranched one.Hope You Like My Answer...By rananeeraj168@gmail.com in facebook
Which of the following nonpolar molecules has the highest boiling point (N2C2H4F2O2 or CS2)?
The molecule N2C2H4F2O2 has a higher boiling point.
How does a substance's boiling point determine its state at room temperature?
If the substance's boiling point is lower than room temperature, it is probably a gas. If the boiling point is higher, it will be a liquid.
Two diatomic molecules with an equal number of electrons and a similar molecular weight are tested for boiling point the difference in boiling point is 150 degrees which is most likely?
the polar molecule has a higher boiling point
Do elements with higher boiling point have longer or shorter molecule chains?
In general they are longer chained molecules.
Can salt water is used to determine the boiling point of water?
No, salt water cannot be used to accurately determine the boiling point of ultrapure water. Salt water boils at a slightly higher temperature than pure water; salt water can be used to determine the boiling point of salt water.

Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
How do you determine less volatile and more volatile?
The higher the boiling point, the less volatile. And vice versa.
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
