Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5%

Experiment 1: Synthesis of Copper Compounds Introduction This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances‚ many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction‚ however it poses its own problems with the amount of substance that is actually yielded

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

Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

In “Helping Students Use Textual Sources Persuasively‚” Margaret Kantz talks about how individuals should read texts to write a synthesis essay. To write a synthesis essay‚ one should be able to come up with an argument and find information from other sources‚ and use them as proofs to back up the argument. First‚ Kantz talks about the mistakes that students usually make when they write this essay. For instance‚ Shirley made a mistake by reading a repeating and telling the story instead of creating

Multistep Synthesis of Tetraphenylcyclopentadienone Author: Instructor: Date work performed: 10.18.2012--10.25.2012 Date work submitted: 11.01.2012 Abstract: The aim of this experiment was to perform a multistep synthesis to form tetraphenylcyclopentadienone. The first step of the reactions was to synthesize benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1

1. In the Luminol synthesis the compound being oxidized was the sodium hydrosulfite. 2. The purpose of the acetic acid is to pronate the dianon organic molecule to make the neutral organic compound‚ Luminol that will crash out of the solvent. If the number of moles were reversed for acetic acid and sodium hydroxide the solution would be very basic‚ and and the amount of Luminol produced would decrease. 3. The cold water was used to decrease the solubility of Luminol in the solvent and prevent further
