cold concentrated HCl to produce tert-butyl chloride. The crude product was distilled to yield a pure tert-butyl chloride. The tert-butyl alcohol‚ together with HCl‚ underwent an SN1 nucleophilic substitution reaction‚ which is composed of three steps—(1) propanation of alcoholic oxygen‚ (2) formation of carbocation‚ and (3) attacking of the nucleophile to the carbocation. The experiment was only able to yield 0.504 grams or 5.21% of the theoretical yield of 9.679 grams‚ which is considered as extremely

The Dumbest Generation Synthesis Essay In the modern world of today‚ the Web is the medium of all information. It is how information is transmitted and created. It’s how information is viewed and immortalized. Why is it then‚ that the Web is making today’s generation “dumber”? It does feel as if we‚ this current generation of people‚ are becoming more blunt and dull. Many professors and scholars point the cause to the our carefree lifestyle‚ the web‚ and the furthering advancement of technology

October 9‚ 2013 Partner(s): Acetylsalicylic Acid Synthesis Theory. This experiment was carried out to see how the hydroxyl group on 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

article but because we are using a plagiarism tool online‚ I thought it would consider direct quotes as plagiarism even if I cite the source in my write up. The article I chose is called‚ “Synthesis of a Genius” by George Kauffman and Steven Chooljian. The area of exploration and discovery that I chose was the synthesis of urea in chemistry. Urea was discovered by Friedrich Wohler‚ in 1828. This discovery ultimately changed the belief at the time that only organic compounds can be created from living
