Part A H,0 (100°C) has a higher boiling point than CH, OH (65°C). There are more hydrogen bonds between water molecules than between alcohol molecules. There are less hydrogen bonds between water molecules than between alcohol molecules. CH, OH has the higher molecular mass than H,O. There are no hydrogen bonds between alcohol molecules while there are plenty of them between water molecules.
