What are dipole forces?

dipole forces describe the form of interaction that may occur between molecules. Like magnets, molecules are often polar; They have positive and negative charges on different sides based on their molecular structure. A positive part of one molecule can attract the negative part of the other and connect them together. There are two different types of dipole forces; Some are permanent and the last last for a moment. Both species have a significant impact on interactions between molecules.

Temporary, instant dipole forces are known as London's dispersion forces. Electrons in atoms are very mobile and can match in such a way that there is a temporary dipole or separation of positive and negative rounds. When it happens with multiple molecules at the same time, short 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 certain time. London Dispersion forces, Despite JEjich relative rarity in individual atoms and molecules are significant because the massive number of atoms or molecules usually present in the substance almost guarantees that at least some of them will interact through immediate dipoles.

permanent dipole forces are known as the interaction of dipole dipole or Keesom interaction and exist between polar molecules. The molecule tends to have a permanent dipole when it consists of atoms that have different electronegativity values. Electnegativity is a feature of atoms or molecules that describes their ability to attract electrons to each other and create links with other atoms or molecules. When atoms with different values ​​of electronegativity of binding and molecules form, they tend to have permanent, different charges on different parts of their structures. When molecules with permanent dipoles are close to other molecules with permanent dipoles there are manyStrong attractive and repulsive interactions between the polar parts of the molecules.

hydrogen bonds are the third type of intermolecular interaction caused by dipole forces and are another form of permanent dipole interactions. They can only occur between hydrogen and other atom, hence the name. The second atom may be oxygen, fluorine or nitrogen. Hydrogen bonds are essentially a stronger form of dipole dipole interactions.

hydrogen bonds are probably the most important of different types of dipole forces due to their effects on water. Water molecules are very polar due to their electronic arrangement and tend to show a large number of hydrogen bonds. Hydrogen atoms on one molecule of water can interact with oxygen atoms on other water molecules. This degree of attraction gives the water many properties necessary for its essential role in the environment of the Earth, such as cohesion and high boiling point. Overcoming hydrogen bonds requires a considerable amount of energy, which gives a velLook stability in an environment that is primarily formed by water.
