Question

what intermolecular forces are important for the molecule below? [check all that apply.] xef4 group of answer choices A. london dispersion forces D. dipole-dipole C. ion-dipole D. hydrogen bonding E. none of these

Answer 1

The correct answer is A. London dispersion forces.

XeF4 (xenon tetrafluoride) is a nonpolar molecule, which means it has no permanent dipole moment. Therefore, it cannot experience dipole-dipole interactions, ion-dipole interactions, or hydrogen bonding. The only intermolecular force that is important for XeF4 is London dispersion forces, which are caused by temporary fluctuations in electron density that create an instantaneous dipole moment. These temporary dipoles induce similar dipoles in neighboring molecules, leading to attractive forces between them.
