Ketones are water-soluble fats that have powerfully beneficial metabolic benefits and also aid in tissue healing. However, they cannot form hydrogen bonds to each other, so their boiling points are not very high. Structure reminder. The small aldehydes and ketones are freely soluble in water but solubility falls with chain length. All aldehydes and ketones are soluble in organic solvents and, in general, are less dense than water. Aldehydes and ketones are polar because they contain a carbonyl group (oxygen is very electronegative compared to carbon). Option 5. ketones are polar molecules because of the presence of the carbon-oxygen double bond. All aldehydes and ketones are soluble in organic solvents and, in general, are less dense than water. The resulting ions produced are soluble in the 4. They are readily transported into tissues outside the liver, where they are converted into acetyl-CoA (acetyl-Coenzyme A)—which then enters the citric acid cycle (Krebs cycle) and is oxidized for energy. Aldehydes and ketones can form hydrogen bonds with water, so small aldehydes and ketones are water-soluble. Physical Properties. five. For example, methanal, ethanal and propanone - the common small aldehydes and ketones - are miscible with water in all proportions. aldehydes are easily oxidized, but ketones are not.
