London Dispersion Forces & Temporary Dipole - Induced Dipole Interactions - Intermolecular Forces

This chemistry video tutorial provides a basic introduction into london dispersion forces also known van der waals forces. London dispersion forces arises from the electrostatic interactions between temporary dipoles and induced dipoles. A dipole is a polarized particle that contains a separation of charge - one part of the particle is partially positive and the other part is partially positive. Polar molecules contain permanent dipoles. Nonpolar molecules do not usually contain a dipole moment but can become a temporary dipole due to the distortion of the electron cloud. Atoms and molecules with a large number of electrons are highly polarizable, that is, they have a higher probability of turning into a temporary dipole. A dipole can cause another molecule to turn into a temporary dipole. This is known as an induced dipole. The interactions between temporary instantaneous dipoles and induced dipoles are known as van der waals interactions or london dispersion forces. Large molecules have a high amount of london dispersion forces and therefore have higher boiling points than smaller molecules. Boiling point is directly related to the amount of van der waal interactions among molecules.

    I think the temporary polar molecule induces the other molecule due to dipole moment which pushes the electrons in the induced molecule not because the electrons are attracted to the positive charge of the inducing molecule as they should have been more attracted to the positive charge of the induced molecule as it is nearer

    The notion that the more electrons you have will increase the probability that 1 side will be unevenly distributed seems counterintuitive. For instance, if you flip a coin twice the chances of getting heads 100% of the time is relatively high (let the coin represent helium with only 2 electrons and heads represent the electrons existing on the same side of the atom). Whereas If you flip a coin 53 times (like iodine) the chances of getting heads 100% of the time (or anywhere close) is very low. Therefore the more electrons an atom has should increase the likelihood that the electrons are evenly distributed the majority of the time as a % value, which in turn should lower the LDF of the atom?

  • @weeztalks

    @weeztalks

    2 жыл бұрын

    It might be because helium has low numbers of electrons so the nucleus can attract them and keep them evenly distributed. Unlike Iodine which has 53 electrons so for e.g if a polar molecule comes near it Iodine nucleus will have a hard time attracting all the electrons and keeping them in their place.
