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. O Water has two O-H bonds and methanol has only one. O Methanol has non-polar carbon chain. O Methanol is an organic compound and water is an inorganic compound. O Methanol 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. OWater evaporates during the mixing. O Methanol evaporates during the mixing. During hydration, methanol molecules decrease in volume. O Water molecules interact extensively with methanol molecules.
