WebA freezing point depression of 1.86 °C occurs for every mole of solute added to 1 kilogram (kg) of water. In other words, if you dissolve one mole of sugar in 1 kg of water, water will no longer freeze at 0 °C, but rather will freeze at –1.86 °C. Freezing point depression is a colligative property, meaning that the effect is observed ...

WebFreezing Points •The stronger the IMF, the higher the freezing point. Freezing Points Why does FP decrease as period ? Freezing Points •Even in non-polar molecules, London dispersion forces can be strong enough to form a solid in cold temperatures. •FP generally decrease down a group as electrons become further from the nucleus and WebJun 30, 2024 · The stronger the IMF, the higher the boiling point will be Take, for example, hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom combines with either nitrogen, oxygen, or fluorine (H_2O). Hydrogen bonding results in the strongest intermolecular forces, and therefore will always have the highest boiling point. Just …
