**Vapor Pressure and Boiling Point Comparison of Compounds A and B**The vapor pressure of compound A is 205 torr at 25°C while the vapor pressure of compound B is 284 torr at the same temperature. Which of the following best applies to the compounds?- **A) Both listed conditions are true.**- **B) Both listed conditions are false.**- **C) The intermolecular forces between A molecules are less than those between B molecules.**- **D) Compound A has a higher boiling point than compound B.****Answer:** To solve this question, one must consider the relationship between vapor pressure, intermolecular forces, and boiling points of compounds. If a compound has lower vapor pressure at a given temperature, it generally means its molecules are held together by stronger intermolecular forces, which increases its boiling point.**Explanation:**- **C) The intermolecular forces between A molecules are less than those between B molecules**, is incorrect because compound A has lower vapor pressure at 25°C than compound B, indicating stronger intermolecular forces. - **D) Compound A has a higher boiling point than compound B**, is correct because stronger intermolecular forces (indicated by lower vapor pressure) usually lead to a higher boiling point.To conclude, vapor pressure is inversely related to the strength of intermolecular forces and directly related to the boiling point of the compound.
