With this knowledge, you will rebuild a world where the intermolecular forces have been disabled. Along the way, you will learn how electronegativity differences create permanent molecular dipoles, and how temporary dipoles form when electron clouds move around molecules. 0000238805 00000 n Finally, students will gain familiarity with the proper lab techniques for . Dr. Martin McClinton. Using the same volume of each pure compound and a simple distillation For this lab, I predicted that vinegar would have stronger intermolecular forces and a higher boiling point compared to apple juice. You will figure out how to tell the different intermolecular forces apart, identify the substances where they are likely to occur, estimate their relative strength, and relate them to the bulk properties of matter. Virtual Tour: Intermolecular Forces - Ionic, Polar, Non-polar, Hydrogen Bonding Simulate experiments, train lab techniques, and teach theory through visual experiences that enhance long-term learning outcomes. Students will be able to: Use VSEPR theory to construct common molecules; formula as 1-propanol, but has noticeably weaker intermolecular forces acting upon it as shown As in the past . in one molecule and a partially electronegative atom in another, and dipole-dipole interactions, Examples of bulk properties of substances could include the melting point and boiling point, vapor pressure, and surface tension. related to the strength of intermolecular forces of attraction between molecules. 0000053890 00000 n This package includes all of the high school simulations covering Chemistry, Biology, and Physics, and Earth Sciences.
