Why is the pka of fluorenone different that other ketones?
9-fluorenone is different because it is a ketone with all of its carbons tied up in double bonds. There are no readily available acidic hydrogens, therefore this makes the pka of the molecule much greater than most other ketones.
Which two groups have the same functional group?
ketones and aldehydes
Why are ketones more reactive towards nucleophiles than esters?
Sp hybridized carbon atom of alkyne pulls the electrons more strongly making he attached Hydrogen atom slightly acidic Becoming more suitable for Nucleophilic attack.In Alkenes no acidic Hydrogen is present.
What types of aldehydes and ketones would you expect to be water-soluble?
The aldehydes and ketones having three or less carbon atoms are soluble in water.
What nutrient is used to form ketones?
protein

Why are ketone pathological conditions associated with vomiting?
Activation of chemoreceptors in the Medulla. Possibly due to the acidic nature of Ketones, this would have an effect on the vomiting centres in the brain.
Which two groups have the same functional group?
ketones and aldehydes
What three features does diabetic ketoacidosis combine?
hyperglycemia, meaning excessively high blood sugar kevels; hyperketonemia, meaning an overproduction of ketones by the body; and acidosis, meaning that the blood has become too acidic.
What is a urinalysis test for ketones?
Ketones are substances created during the breakdown of fat in order to become energy when there is not enough sugar in the body. Ketones can be found in the blood or in the urine.
Could the metabolism of fat explain the presence of ketones and the low pH of the urine?
Yes, metabolism of fats is a reason and can cause the presence of ketones and can lower pH levels. To make it simple, ketones form from rapid or incomplete oxidation (breaking down) of fats from the liver and forms ketones. Ketones are strong acids and this is why it can cause a lowering of pH in the urine.
What is 4 plus ketones?
This would mean that there would be four or more ketones (C=O) in a molecule.
How does ketones react with sodium bicarbonate?
Ketones or Aldehydes DO NOT react with Sodium Bicarbonate..generally only Carboxilic acids have the ability to do it!
What are the chemicals released by ketosis?
ketones
Does ketones contain nitrogen atoms?
NO they do not
What is normal level for ketones?
Zero.
Tollen's test on ketones?
A Silver mirror does not appear as ketones cannot be further oxidized unlike aldehydes in which a silver mirror does appear.
