Let's compare two compounds of similar molar mass in which A is comprised of nonpolar molecules and B composed of polar molecules. Which of the following statements is true?

Question

Quizplus · Accepted Answer

Polar molecules (compound B) have stronger intermolecular forces (like dipole-dipole interactions) compared to nonpolar molecules (compound A), which mainly rely on weaker London dispersion forces. Therefore, more energy (higher temperature) is required to overcome these forces in polar molecules, leading to a higher boiling point for compound B.
