Dipole Moment: This term refers to the measure of polarity in a chemical species.
Hydrophilic: These are substances that can mix with or dissolve in water. Polar substances tend to be hydrophilic because they can form hydrogen bonds with water.
Electronegativity:This term describes an atom's ability to attract shared electrons towards itself. The difference in electronegativity values determines whether a bond will be nonpolar or polar.
