experiment was to synthesize acetanilide by the acetylation of aniline and to purify crude acetanilide product by recrystallization. The group determined water as the recrystallizing solvent. The group performed acetylation of aniline and acetic anhydride for the formation of crude acetanilide. The recrystallizing solvent dissolved the crude acetanilide and was heated in a water bath‚ after heating‚ the solution was cooled in an ice bath causing crystals to form. The percent recovery was computed

To get to aniline‚ tin metal acts as a reducing agent and is oxidized to SnCl4. The purification of crude aniline is done by distillation and extraction. Aniline can be converted to acetanilide by acetylation reaction using acetic anhydride with sodium acetate. This step protects the amine functional group from doing unwanted reactions during chlorosulfonation and amination steps. The chlorosulfonyl group attacks in the para position to the acetamide group‚ by electrophilic aromatic

temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride‚ was used as the pure organic compound. Crude acetanilide underwent crystallization process using the preferred recrystallizing solvent‚ water. The crystallization process was when crude acetanilide was placed in hot water bath and was cooled after

Five hydrocarbons were used namely hexane‚ cyclohexene‚ toluene‚ naphthalene (in hexane)‚ and the unknown (which will be known through parallel chemical tests). Three tests‚ nitration test‚ bromine test and basic oxidation test were conducted to fully differentiate each type of hydrocarbon from one another. Nitration

the benzene ring in salicylic acid reacts with acetic anhydride to form an ester‚ and to make aspirin. Synthesis of Acetylsalicylic Acid occurs by protonation of carbonyl (C=O) group‚ and a nucleophilic attack of OH on the acetic anhydride. The ferric chloride test and melting point were used to test the purity of the results. A hypothesized recovery rater of above 50% was expected. salicylic acid acetic anhydride Acetylsalicylic acid

The father shows his son how to find water using an alder branch. The son never really thought about the lesson. He then moves on with his life by getting married‚ having children and travelling. Climax: The climax is when it the story says “T he alder stayed motionless in my hands and the water beneath the earth refused to sing.” Because we knew he lost the gift at that point. Conclusion: When the narrator tried to put their father’s teaching in action by holding the alder branch waiting for it to writhe
