induceddipólové

Induced dipoles refer to temporary or transient electric dipoles that arise within an atom or molecule due to the influence of an external electric field. This field distorts the electron cloud surrounding the atomic nuclei, causing a slight separation of positive and negative charges. Even in nonpolar molecules, which normally have no permanent dipole moment, an induced dipole can be created. This phenomenon is a fundamental aspect of intermolecular forces, particularly London dispersion forces, which are crucial for explaining the physical properties of many substances. The strength of the induced dipole is proportional to the strength of the external electric field and the polarizability of the atom or molecule. Polarizability is a measure of how easily the electron cloud can be distorted. Stronger electric fields and more polarizable species lead to larger induced dipoles. This temporary charge separation results in an attractive force between molecules, even if they are not permanently polar. Understanding induced dipoles is essential in fields ranging from chemistry and physics to materials science, as it helps explain phenomena like solubility, boiling points, and the behavior of dielectric materials. The interaction between induced dipoles and permanent dipoles, or between two induced dipoles, forms the basis of van der Waals forces, which play a significant role in molecular aggregation and biological processes.
