Van Der Waal forces

Postby Andrea Raymundo 1B » Wed Jun 13, 2018 12:53 am

could anyone explain to me what the differences are between diople-dipole forces, london forces, ion-dipole, and hydrogen bonding?! How could we identify them when given molecular substances? Like in question 6.1

Do Van Der Waals forces act differently in different physical states (solid vs. liquid vs. gas)?

Dipoles have intermolecular forces that are between two or more different molecules. Dipole-dipole forces are between opposite partial charges on two different polar molecules that wants to attract each other. In an induced dipole-dipole, it is a coercive force in which the one causes the other to be a dipole to have intermolecular forces. Lastly, induced dipole-induced dipole/london dispersion/Van der Waal are both non-polar and the weakest intermolecular force; however, it occurs due to electrons in an atom rearranging itself to have one partial positive and one partial negative area. This way the positive region of one atom feels attracted to the negative region of the other.
