Question

Rank the compounds in each Group from fastest to slowest rate of evaporation. For each compound in the Group, state all of the intermolecular forces and use these IMFs to rank the compounds from fastest to slowest rate of evaporation. Be sure to include molar mass considerations where appropriate. Explanation of how these rankings compare to one another. Lastly Clearly explain what must be true of intermolecular forces for a compound to be called “volatile”.

Group A: 2-propanol, pentane, acetone

Group B: pentane, hexane, acetone

Group C: ethanol, 2-propanol, acetone
