Ketones primarily exhibit dipole-dipole interactions and London dispersion forces as their intermolecular forces (IMFs). The presence of a carbonyl group (C=O) in ketones creates a polar bond, allowing for significant dipole-dipole interactions. Additionally, while ketones can engage in hydrogen bonding as hydrogen bond acceptors due to the electronegative oxygen, they do not form hydrogen bonds as donors since they lack an O-H or N-H bond.

What is ketoturia?
The proper term is "ketonuria." It is when ketones are present in urine.
How can one detect the presence of ketones in urine without the presence of glucose?
One can detect the presence of ketones in urine without the presence of glucose by using ketone test strips, which change color when ketones are present. These strips can be dipped in a urine sample and the color change can be compared to a color chart to determine the level of ketones.
What are the possible reasons for the presence of ketones in urine?
Ketones in urine can be present due to factors such as fasting or low carbohydrate intake, uncontrolled diabetes, excessive alcohol consumption, or certain medical conditions like ketoacidosis.
Why does propanone has higher vapour pressure than ethanol at room temperature?
The intermolecular forces (IMFs) that attract propane molecules to eachother is far weaker than the IMFs of ethanol molecules. Consequently there is less of an energy barrier for a propane molecule to evaporate. IMFs of propare are limited to the london dispersion forces, which are the weakest IMFs IMFs of ethanol are the london dispersion forces as well as the dipole-dipole interaction (- charge on oxygen and positive on hydrogen) and hydrogen bonding (very strong IMF)
Are ketones acidic in nature?
Yes, ketones are slightly acidic in nature.

Why this test is positive only for ketos?
Do you mean ketones? Ketones are a by-product of fat breakdown. When a person is not eating enough carbohydrates (bread, pasta, rice, potatos) for their energy needs the body starts using its fat stores for energy and ketones show in the urine. It may also be a sign of diabetes. If I haven't answered the question you asked please ask as something different.
Can sodium borohydride reduce ketones?
Yes, sodium borohydride can reduce ketones.
Are ketones in urine the same as protein in urine?
No, ketones in urine and protein in urine are not the same. Ketones are byproducts of fat metabolism, typically present when the body is using fat for energy instead of carbohydrates, often seen in conditions like diabetes or fasting. Protein in urine, or proteinuria, can indicate kidney damage or disease, as healthy kidneys usually prevent significant amounts of protein from leaking into urine. Thus, the presence of ketones and proteins in urine reflects different metabolic processes and health conditions.
What is a urinalysis test for ketones?
A urinalysis test for ketones is done to measure the level of ketones in the urine. Ketones are produced when the body breaks down fat for energy, typically seen in conditions like uncontrolled diabetes or during fasting. High levels of ketones in the urine can indicate a state of ketosis or ketoacidosis.
Are ketones acidic?
Yes, ketones are weakly acidic compounds. The acidity of ketones is due to the presence of a carbonyl group, which can release a proton to form a resonance-stabilized enolate ion. However, compared to carboxylic acids, ketones are relatively weaker acids.
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.
