Well, what are the normal boiling points of each liquid....?

Explanation:

#"Acetone"# #56.0# #""^@C#.

#"Ethanol"# #78.5# #""^@C#.

#"Peanut oil"# #230# #""^@C#.

#"Glycerol"# #290.0# #""^@C#.

You don't have to remember these boiling points, but you should be able to interpret them.

On this basis, CLEARLY, glycerol has the greatest intermolecular interaction, the greatest intermolecular force. What is special about glycerol, that individual molecules should have this degree of interaction. Can it be related to the boiling point of water, whose normal boiling point is anomalously high?
