The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine. Aside from Caffeine‚ Acetaminophen has one amide functional

The lone active ingredient of Tylenol was acetaminophen with an Rf value of 0.39. The elution sequence obtained in the experiment is as follows: ibuprofen (least polar)‚ acetylsalicylic acid‚ acetaminophen‚ and caffeine (most polar).

Panacetin is typically made up of sucrose‚ aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on their solubilities and acid-base

Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment‚ chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However‚ nowadays‚ both coloured and colourless compound are used in chromatography by various methods. In chromatography‚ the separation process of mixture is mainly based upon the polarity and molecular weight of sample
