Question

Which of the following statements is FALSE?

-The rate of vaporization increases with increasing temperature.
-The rate of vaporization increases with decreasing strength of intermolecular forces.
-The rate of vaporization increases with increasing surface area.
-Molecules with hydrogen bonding are more volatile than compounds with dipole-dipole forces.
-None of the above is false.

Answer 1

The false statement is that molecules with hydrogen bonding are more volatile than compounds with dipole-dipole forces, which is incorrect since hydrogen bonds result in higher boiling points and lower volatility.

Step-by-step explanation:

The student asked which of the following statements is FALSE:

1. The rate of vaporization increases with increasing temperature.
2. The rate of vaporization increases with decreasing strength of intermolecular forces.
3. The rate of vaporization increases with increasing surface area.
4. Molecules with hydrogen bonding are more volatile than compounds with dipole-dipole forces.
5. None of the above is false.

The false statement here is: "Molecules with hydrogen bonding are more volatile than compounds with dipole-dipole forces." In fact, hydrogen bonding is a type of dipole-dipole interaction but is much stronger than most other forms of dipole-dipole attractions due to the higher electronegativity of certain atoms involved, such as fluorine, oxygen, or nitrogen. Substances that can form hydrogen bonds tend to have higher boiling points and are less volatile compared to those that can't form hydrogen bonds but only have dipole-dipole interactions.
