Electrostatic potential

Postby Susie Lee 2I » Tue Nov 14, 2017 11:28 am

In class, Prof. Lavelle mentioned that polar molecules interact with an electrostatic potential. Can someone expand on this?

Electrostatic potential has everything to do with dipole moments, electronegativity, and partial charge. Electrostatic potential helps us to know the relative polarity of a molecule. Negative electrostatic potential corresponds to a attraction of a proton by the concentrated electron density in the molecule. Positive electrostatic potential corresponds to repulsion of the proton by the atomic nuclei in regions where low electron density exists. When a proton approaches a positive region of the molecule, the repulsive interaction results in increasing positive potential energy. When a proton approaches a negative region, an attractive interaction results in negative potential energy.
