WebDec 29, 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. Webinteractions between molecules. This stronger IMF influence holds the glycerol molecules together better. Outcomes: 8,13,14,15 5.
