Synthesis of MAVA copolymer. It is produced industrially on a large scale, but occurs in nature only in trace amounts. Methyl Ethyl Ketone is a clear low viscosity liquid with a mild acetone like odor; miscible in oil, soluble in water. 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. 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. Copy.
