Molecular forces - Study guides, Class notes & Summaries

Intermolecular forces - L6 Exam 2023/2024 what are the three intermolceular forces (in order of increasing strength)? - ANSWER-1. Van der Waals forces - act between all atoms and molecules 2. Permanent dipole-dipole forces - act between molecules with permanent dipoles (polar molecules) 3. Hydrogen bonds - only when H is bonded to F, O or N VDW forces application - ANSWER--Consider He (number of electrons = 2). He atoms move randomly & its two e-s could be anywhere in the 1s orbital. At ...

Chem 162 Experiment #3: Intermolecular Forces Part II: Vapor Pressure and Enthalpy of Vaporization PURPOSE (4 pts) The purpose is to measure the enthalpies of vaporazation of pentane, diethyl ether, butanone, and 2-butanol. For each of these molecules, a portion of the enthalpy of vaporization is due to dispersion forces (all molecules have dispersion forces) and the other to a polar component. In the boxes provided below, draw the structural formula for each molecule (should be drawn by h...
