Glycerol boils at a higher temperature than water. what does this indicate about the attractive forces of glycerol? they are nonexistent. they are the same as those in water. they are stronger than those in water. they are weaker than those in water.

They are stronger than those in water.

Explanation:

The attractive forces in the substances are responsible for the molecules to be together. If we want to boil a substance, we need to break these forces, so the molecules can be separated in the gas phase. As stronger is the force, as difficult is to break it, and more energy is necessary to do it, so the boiling temperature is higher.
