What Are Dipole Forces?
Dipole forces describe a form of interaction that can happen between molecules. Like magnets, molecules are often polar; they have positive and negative charges on different sides based on their molecular structure. The positive part of one molecule can attract the negative part of another, drawing them together. There are two different types of dipole forces; some are permanent and some last only for an instant. Both kinds have a significant impact on the interactions between molecules. Temporary, instantaneous dipole forces are known as London dispersion forces. Electrons in atoms are very mobile and can align in such a way that a temporary dipole, or separation of positive and negative charges, occurs. When this happens to multiple molecules at the same time, brief attractive or repulsive forces can occur. This process is based on the probability that the arrangement of electrons in a given atom or molecule will exist in a specific way at a specific time. London dispersion forces, d
