Question

A fellow student say , " All substance experience London disperison forces of attraction between particle." Is this etatement true? Explain your answer

Answer 1

Yes, it is true. Here is a site to help you identify the reason.

Answer 2

The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction. London forces are the attractive forces that cause nonpolar substances to condense to liquids and to freeze into solids when the temperature is lowered sufficiently.

Because of the constant motion of the electrons, an atom or molecule can develop a temporary (instantaneous) dipole when its electrons are distributed unsymmetrically about the nucleus.

Answer 3

That sounds ok BUT you are guilty of plagiarism if you don't put it in your own words. Here is a definition of plagiarism.
