Quizplus · Accepted Answer

Water has strong hydrogen bonds, which are a type of dipole-dipole interaction. These strong intermolecular forces mean that water will have a lower vapor pressure at a given temperature compared to substances with weaker intermolecular forces. Curve (c) represents a substance with relatively low vapor pressure over a range of temperatures, consistent with the properties of water.
