Which of the following is true regarding the origin of dipole forces between molecules? They result from the attraction of the permanent positive and negative ends of separate polar molecules. The result from the attraction of temporary regions of positive and negative charges that arise in the molecules. They result from the attraction between positive and negative ions. They result from interactions between highly electronegative atoms like nitrogen, oxygen, and fluorine attached to hydrogen

Answer 1

The correct answer is: They result from the attraction of temporary regions of positive and negative charges that arise in the molecules.Dipole forces, also known as van der Waals forces or London dispersion forces, are the weakest type of intermolecular force. They arise due to temporary fluctuations in electron density within molecules, which create temporary dipoles. These temporary dipoles induce dipoles in neighboring molecules, leading to an attractive force between them. This type of force is present in all molecules, whether polar or nonpolar, and is the only intermolecular force in nonpolar molecules.
