Different types of dipole moments?

Postby Sarai Viveros 1K » Sun Jun 03, 2018 2:32 pm

I know there are different types of dipole moments, but what are they and what are the differences between them? Which ones should we know?

A dipole moment is when atoms in a molecule share electrons unequally. This occurs when one atom is more electronegative than another.

By different types, do you mean a dipole-dipole and dipole-induced-dipole interaction?

Dipole dipole is a type of intermolecular attraction, which is a attraction between two molecules. Dipole-dipole interactions are electrostatic interactions between the permanent dipoles of different molecules and so the partially negative side of a polar molecule is attracted to a partially positive side of another polar molecule.

Dipole induced dipole is a weak intermolecular attraction, and it is when a polar molecule causes a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons (i.e. the partially negative side in a polar molecule repels the e- in the nonpolar molecule, causing one side to be partially positive, so the polar molecule's partially +ve side can be attracted to the partially positive side of the nonpolar molecule) in the nonpolar species.

I also am a bit confused as to which we need to know. There were many different types introduced in one lecture, but which ones should we know, and to what extent?

You should know all since they were all introduced in the lecture.
