Polar and Nonpolar Molecules

Postby Kimberly 1H » Sat Nov 10, 2018 11:43 pm

Why do polar and nonpolar molecules not mix well, such as oil and water? Does it have to do with having different shapes or dipole/no dipole moments?

Polar molecules have two parts with opposite charges that attract to one another, but non polar molecules do not have dipole, therefore they do not have opposing charges.

The water molecules are more attracted to one another (dipoles) than to the oil molecules. The oil molecules are said to be hydrophobic and do not mix with water for this reason.

Since an increase in size and molar mass results in stronger attractive interactions, does that mean that it also increases the polarizability of an atom?

Nonpolar molecules. A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule.
