Place the following compounds in order of increasing vapor pressure. rubbing alcohol [ (ch3)2choh) ]; propane, diethyl ether (ch3ch2-o-ch2ch3) a. diethyl ether < propane < rubbing alcohol b. diethyl ether < rubbing alcohol < propane c. rubbing alcohol < propane < diethyl ether d. propane < diethyl ether < rubbing alcohol e. propane < rubbing alcohol < diethyl ether f. rubbing alcohol < diethyl ether < propane

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

Ans : F
