a.
To distinguish:
Between
Introduction:
Nonpolar molecules are hydrophobic because they usually lack the ability (intermolecular forces) to interact with water molecules. They usually lack the ability to form hydrogen bonds, ionic bonds, or have any sort of dipole interaction with water. Since they cannot interact with water molecules on a molecular level, they tend to stay by other nonpolar molecules (molecules which they can interact with, hence oil and water do not mix very well or at all).
b.
To distinguish:
Between ionic interactions and polar interactions.
