Quizplus · Accepted Answer

The increased boiling point of ketones compared to alkanes and ethers of similar molar mass is due to dipole-dipole interactions. Ketones have a polar carbonyl group, which results in a dipole moment. The carbonyl group interacts with other polar molecules through dipole-dipole interactions, increasing the boiling point. Alkanes and ethers lack polar groups, so they cannot interact through dipole-dipole interactions, leading to lower boiling points.
