Question

Which of the following statements is true about water? It has a boiling point lower than methane
It has a viscosity higher than glycerol
It has a molar heat of vaporization higher than acetone
It is not soluble in ethanol

Answer 1

Answer:

Water has a higher boiling point because the hydrogen bonds that form water molecules are stronger than the Van der Waals interactions among methane molecules, therefor more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state
