What Are Dipole Forces?

Dipole-dipole interaction is the most common type of interaction between polar molecules, that is, the attraction between one end of a polar molecule with a partially positive charge and the other end with a partially negative charge. For example, a hydrogen chloride molecule is a polar molecule. As a result of the electronegativity of a chlorine atom attracting electrons, one end of the chlorine atom is partially negatively charged, the hydrogen atom is partially positive, and the positive end of a hydrogen chloride molecule. The end is attracted to the negative end of another hydrogen chloride molecule, and this interaction is a dipole-dipole interaction. ^[1]

characteristic

Polar molecules have dipole moments due to uneven charge distribution, which is represented by " ", so when polar molecules approach, they will cause electrical attraction. This kind of force is called dipole-dipole force. The greater the molecular dipole moment, the greater the intermolecular force.
