[References] a. Account for this fact: Although methanol (CH3OH) (bp, 64.7 °C) has a higher molar mass than water (bp, 100 °C), the alcohol has a lower boiling point. Methanol has non-polar carbon chain. Methanol is an organic compound and water is an inorganic compound. Water has two O-H bonds and methanol has only one. OMethanol has more hydrogen atoms per molecule. b. Account for this fact: Mixing 50 mL of methanol with 50 mL of water produces a solution with a volume slightly less than 100 mL. Methanol evaporates during the mixing. During hydration, methanol molecules decrease in volume. Water evaporates during the mixing. Water molecules interact extensively with methanol molecules.
