4) is correct
This is because water is polar and it will mix with a polar solvent. A good rule for remembering the behavior of non-polar and polar compounds when it comes to being miscible is that "like dissolves like."
Vapor pressure is the pressure which is exerted by the vapors of a liquid in equilibrium with the liquid. Vapor pressure depends on the boiling point; lower the boiling point higher will be the vapor pressure.
Based on the given compounds:
rubbing alcohol is polar and has the strongest intermolecular force of attraction followed by relatively polar ether and finally the non-polar propane.
The increasing order of boiling point will be:
propane < diethyl ether < rubbing alcohol
Thus, the increasing order of vapor pressure will be:
rubbing alcohol < diethyl ether < propane
