Panacetin‚ a type of pain-killer. 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 properties. Then‚ the percent composition of Panacetin can be deduced based on the masses

2-naphthol‚ and naphthalene. These organic solids are purified by partitioning the solid in 2 immiscible solvents‚ diethyl ether and sodium bicarbonate or sodium hydroxide. II. Significance a. The significance of the Extraction lab is to purify Acetanilide benzoic acid‚ 2-naphthol‚ and naphthalene by determining the partition coefficient. This value is determined by dividing the solubility of the given solute in the extraction solvent (Sodium bicarbonate or Sodium hydroxide)) by the solubility in

Unsaturated Hydrocarbons Unsaturated hydrocarbons Have fewer hydrogen atoms attached to the carbon chain than alkanes. Are alkenes with double bonds. Are alkynes with triple bonds. 1 Structure of Alkenes Alkenes (and alkynes) are unsaturated hydrocarbons Alkenes have one or more double bonds The two bonds in a double bond are different: - one bond is a sigma () bond; these are cylindrical in shape and are very strong - the other is a pi (π) bond; these involve sideways overlap of

which undergoes a rapid de-protonation by the base in the second step to restore aromaticity (Figure 3). E H E H + E+ E H fast E + HB+ B Figure 3. Some common electrophilic aromatic substitution reactions are: halogenation‚ nitration‚ sulfonation‚ Friedel-Crafts Acylation and Friedel-Crafts alkylation.

Premium Electrophilic aromatic substitution Organic reaction Chemical reaction
This experiment focuses on the concept of electrophilic aromatic substitution‚ which is a type of benzene reaction. This reaction consists usually of benzene and an electrophile. The role of the nucleophile is played by the double bond on the benzene ring. IT will react will the electrophile and this reaction will form a carbon cation intermediate. With additional reactions with a base‚ the electrophile fundamentally replaces the hydrogen of the benzene. Benzene is classified as one of the countless

Panacetin contains sucrose‚ aspirin and an unknown which can be acetanilide or phenacetin in which phenacetin was created and weighed. Introduction In this lab our basic goal was to make the sucrose‚ aspirin and unknown that are formed from pharmaceutical panacetin. In doing this lab we used NaOH and diethyl either‚ along

color change or a warming effect. Flammability was tested by igniting 3-5 drops of the sample in a small evaporating dish. Baeyer’s test and Bromine test were used for tests for active unsaturation. Aromaticity of the compound was determined through nitration. Oxidation was tested by introducing 8 drops of 2% KMnO4 solution and 3 drops of 10% NaOH solution to 4 drops of the sample organic compound in a test tube and warming the mixture through water bath. All of the test compounds are liquid and colorless
