Answer;

Water has the highest normal boiling point and methanol on the other hand has the lowest boiling point.

Explanation;

-The normal boiling point is the temperature in which the vapor pressure of a liquid becomes equal to atmospheric pressure.If the inter-molecular forces are small, the liquid has a high vapor pressure. Little heat energy will have to be added to separate the molecules, so the boiling point will be low.

-Boiling points and equilibrium vapor pressure are inversely proportional, because less heat is required to raise vapor pressure to reach atmospheric pressure.

-Therefore, since water has the lowest vapor pressure, water it has the highest boiling point and since methanol has the highest vapor pressure it has the lowest boiling point.
