In this example, most of the molecule is nonpolar (the long C-H tail) with just a small part at the right end being polar. 0.917-0.923 As you can see, Peeps seem about as happy in acetone as they are in water. Although water and oil are polar and non-polar, respectively, acetone is soluble in both. Oleic acid, found in olive oil, is soluble in hexane but not soluble in water.

Substances may combine together poorly or very well, and it's possible to describe solutions as "partially soluble" or "mostly soluble." In the former, the oil seeds are subjected to external pressure and in the latter use is made of organic solvents, which dissolve the oil when brought into contact with the oil bearing material. This is the reason for acetone solubility in oil and water. The methods of extraction of vegetable oils from the oil seeds are mechanical expression and solvent extraction. <<
