Consider two flasks that contain different pure liquids at 20°C.

The liquid in one flask, substance A, has a molar mass of 100 g/mol and has hydrogen bonding. The liquid in the other flask, substance B, has a molar mass of 105 g/mol and has dipole€“dipole interactions.
a. If the molecular structures of the compounds are very similar, which flask probably contains substance A?
b. If you were to increase the temperature of each of the flasks by 15°C, how would the pictures change (assume that you stay below the boiling points of the liquids)?
