Imfs and freezing point
Witryna29 gru 2024 · 3.1 Intermolecular Forces. 7 min read • december 29, 2024. Dalia Savy. Kanya Shah. Intermolecular forces (IMFs) are the attractive or repulsive forces between entire molecules due to differences in charge. Many students confuse IMFs with intramolecular forces, which were the center of the last unit. WitrynaPentane has five carbons, one, two, three, four, five, so five carbons for pentane. And pentane has a boiling point of 36 degrees Celsius. Hexane has six carbons, one, two, three, four, five, and six. So six carbons, and a higher boiling point, of 69 degrees C. Let's draw in another molecule of pentane right here.

The former is termed an intramolecular attraction while the latter is termed an … WitrynaAboutTranscript. A liquid’s vapor pressure is directly related to the intermolecular forces present between its molecules. The stronger these forces, the lower the rate of evaporation and the lower the vapor pressure. Created by Sal Khan.
