Water and oil do not mix because water molecules are nonpolar and molecules that compose oil are generally polar.

Question

Quizplus · Accepted Answer

Water molecules are polar, meaning they have a partial negative charge on one end and a partial positive charge on the other end. Oil molecules, on the other hand, are nonpolar, meaning they have an even distribution of charge throughout the molecule. This difference in polarity causes water and oil to be immiscible and not mix together.
