Question

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.

Answer 1

They are stronger than those in water.

Step-by-step explanation:

The attractive force between the particles of glycerol is stronger than that of water, so more heat energy is required to overcome this force and change it into gaseous form, that's why it boils at a higher temperature than water.
