Which of the following types of molecules would you expect to have the highest vapor pressure at a given temperature?
A) nonpolar molecules, because there are few intermolecular forces holding them together
B) nonpolar molecules, because there are many intermolecular forces holding them together
C) polar molecules, because there are some intermolecular forces holding them together
D) ionic compounds, because there are many intermolecular forces holding them together
E) ionic compounds, because there are few intermolecular forces holding them together

Question

Quizplus · Accepted Answer

Nonpolar molecules have weak intermolecular forces, so they are more likely to evaporate and have a higher vapor pressure at a given temperature compared to polar molecules or ionic compounds which have stronger intermolecular forces.
