A Solution Is Made by Mixing Acetone and Methyl Alcohol

A solution is made by mixing acetone and methyl alcohol, whose structures are shown as I and II below. Which statement below best describes the characteristics of this mixture? Hint: How does the strength of hydrogen bonds compare to other intermolecular forces?

A) Because the intermolecular forces for acetone-acetone, methanol-methanol, and acetone-methanol interactions are comparable, the mixture behaves as an ideal solution.
B) Because the intermolecular forces for acetone-methanol interactions are weaker than either the acetone-acetone or methanol-methanol interactions we should observe a positive deviation from ideal solution behavior.
C) Because the intermolecular forces for acetone-methanol and methanol-methanol interactions are stronger than the acetone-acetone interactions due to hydrogen bonding, the experimental vapor pressure would be lower than calculated by Raoult's Law.
D) Because the intermolecular forces for methanol-methanol interactions are weaker than either the acetone-acetone or acetone-methanol interactions due to hydrogen bonding, the experimental vapor pressure would be greater than calculated by Raoult's Law.
E) Because the intermolecular forces for methanol-methanol interactions are weaker than either the acetone-acetone or acetone-methanol interactions due to hydrogen bonding, the experimental vapor pressure would be lower than calculated by Raoult's Law.
