From most polar to least:
Caffeine, Acetaminophen, Aspirin
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
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.
Excedrin contains acetaminophen (tylenol), aspirin, and caffeine. Tylenol is acetaminophen.
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.
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.
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.
No caffeine in Tylenol 3 that is made in the US. In Canadian formulations of Tylenol 3 there may be found 15mg of caffeine.
The active ingredients are acetaminophen, aspirin, and caffeine.
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.
caffeine is polar due to the amines group and it is basic
Acetaminophen, aspirin, caffeine
Phenacetin will have a higher Rf value than acetaminophen in a TLC separation on silica gel using a non-polar developing solvent. This is because phenacetin is more non-polar than acetaminophen, causing it to move further up the TLC plate and have a higher Rf value.
