There are many things that determine whether something is polar or nonpolar, such as the chemical structure of the molecule. The carbonyl group is polar because the electronegativity of the oxygen is greater than that for carbon. Thus, ketones are nucleophilic at oxygen and electrophilic at carbon. Because the carbonyl group interacts with water by hydrogen bonding, ketones are typically more soluble in water than the related methylene compounds. This knowledge can be used for other forms of esters, such as ethyl acetate. pentane, hexane, benzene, kerosene, gasoline, some in acetone, methyl ethyl ketone, generally anything non polar with a low molecular weight What solvent does the acronym MEK identify?

It is more polar than ethyl acetate & also more polar than MEK (i.e. The boiling point temperature of acetone (2-propanone) is 56.2 °C, and the boiling point temperature of methyl ethyl ketone (MEK or 2-butanone) is 79.6 °C. Now, a bond is generally considered polar if the electro negativity difference between the two bonded atoms is greater than or equal to 0.5. So, C-H bonds are not considered as polar.Hence the ethyl group is almost non-polar. But, it is the O-H bond that causes polarity to the ethanol molecule.
