Why Do Oil and Water Not Mix?

Answer

Oil and water don't mix due to the fact that oil is made up of non-polar molecules while water on the other hand consists of polar molecules. Although both of them are liquids, their chemical compositions are very dissimilar from each other. Oil is made of long non polar hydrocarbons meaning it experiences weak forces of attraction while water molecules have one end positively charged while the other negatively charged.
