Polarity order of ibuprofen Aspirin acetaminophen and caffeine?
Caffeine > Acetaminophen > Ibuprofen > ASA Actually ASA is more polar than Ibuprofen. In ethanol ASA rf value is around .7 and Ibuprofen is around .77. Should be Caffeine > Acetaminophen > ASA > Ibuprofen Rf in ethanol Caffeine < Acetaminophen < ASA < Ibuprofen
Is caffeine more soluble in acetone or methylene chloride?
Caffeine is more soluble in methylene chloride than in acetone. Methylene chloride is a non-polar solvent, while caffeine is a polar compound. Polar compounds like caffeine tend to be more soluble in non-polar solvents like methylene chloride.
Is aspartame more polar than caffeine?
Yes, aspartame is more polar than caffeine. Aspartame, being a dipeptide composed of amino acids, contains multiple polar functional groups, such as carboxyl and amine groups, which increase its overall polarity. In contrast, caffeine, while also polar due to its nitrogen atoms, has a more hydrophobic structure and fewer polar functional groups. Thus, aspartame's molecular structure contributes to its higher polarity compared to caffeine.
What are the components of excedrin and Tylenol?
Excedrin contains acetaminophen (tylenol), aspirin, and caffeine. Tylenol is acetaminophen.
Is acetaminophen non polar or polar?
Acetaminophen is polar due to the presence of hydroxyl (OH) and amide (CONH2) groups in its structure. These functional groups result in uneven distribution of electron density within the molecule, making it polar.
Is caffeine more miscible in organic layer (dichloromethane) or aqueous layer?
Caffeine is more miscible in the organic layer (dichloromethane) than in the aqueous layer. This is because caffeine is a non-polar compound and thus dissolves better in organic solvents than in water, which is a polar solvent.
Does polar orange dry diet have caffeine?
No. Polar Soda flavor Orange Dry does not contain caffeine. In fact, according to a spokeswoman at Polar Beverages, none of their soda contain caffeine. The only product that contains caffeine is their tea beverage.
How much caffeine in Tylenol 3?

What is the active ingredient in Excederine?
The active ingredients are acetaminophen, aspirin, and caffeine.
Does Excedrin have aspirin in it?
It is a mixture of the active ingredient in Tylenol combined with aspirin and some caffeine. Excedrin Migraine is the only Excedrin with aspirin. It has: 250mg of aspirin, 250mg of acetaminophen, and 65mg caffeine.
What is the polarity of caffeine?
caffeine is polar due to the amines group and it is basic
Is adenosine or caffeine more soluble?
Adenosine is generally more soluble in water compared to caffeine. Adenosine is a polar molecule with multiple hydroxyl groups that enhance its solubility. In contrast, caffeine, while also soluble, has a less polar structure due to its methyl groups, making it less soluble than adenosine. Therefore, adenosine has a higher solubility in aqueous solutions than caffeine.
