Arrange the following compounds in order of decreasing boiling point,putting the compound with the highest boiling point first.

Question

Quizplus · Accepted Answer

Compound III has the highest boiling point because it has the strongest intermolecular forces due to the presence of hydrogen bonding between the C-O and H-N bonds. Compound I has the next highest boiling point due to dipole-dipole interactions, but it does not have hydrogen bonding. Compound II has the lowest boiling point because it is nonpolar and therefore has the weakest intermolecular forces. Therefore, the correct order is III > I > II.
