A Multistep Synthesis for an Advanced Undergraduate Organic Chemistry Laboratory

hexaphenylbenzene synthesis multistep lab report

Reflux mechanism was used for the reaction to occur. The active site is the part of the enzyme where substrate binds. Because this lab is qualitative rather than quantitative, there are no calculation. When the hydrate metal salt crystal is heated, the attractions to the water are broken by the heat energy and the water escape from the crystal. Course topics include stoichiometry, inorganic nomenclature, solutions, gas laws, thermochemistry, atomic structure, and chemical bonding. Mass a beaker and record 4. Incomplete combustion is the reaction of an.

The product of the Diels-Alder. We will record data based on the concentration, temperature and catalyst for each experiment. Mp Observed Mp Crude product 276. In part A, maleic anhydride and cyclopentadiene were used. Recrystallization followed to purify the product. I believe the exact error was heating the sample too quickly, not allowing the thermometer to display the correct temperature of the apparatus.

The Diels- Alder reaction is one of the most important reactions in all of organic chemistry because of the applicability of it. The molecule in an enzyme upon which the enzyme act is the substrate, which binds reversibly to the active site of the enzyme. Part C began by adding the benzil product 2. Mixtures can be classified into homogeneous and heterogeneous. The mixture was then poured into a beaker with 40ml of cold water and stirred until a yellow solid formed.

Purpose: The purpose of these experiments. To predict the solubility of an unknown Group 2A salt based on the determinations made. This reaction is best used for making six membered rings with different functional groups. Part 1: Find the Volume of One Drop of Solution 2. The foam you made is special because each tiny foam bubble is filled with oxygen. The ylide carries out a nucleophilic attack upon the carbonyl group of the aldehyde, forming an intermediate that can interact with a new benzaldehyde molecule to form a compound structure.

Melting point was then determined 85°C as well as weight 2. As you progress further in science, you will see variations in styles of lab reports, though they all contain the same basic principles. Atom, Chemical compound, Chemical reaction 1208 Words 11 Pages Lab Report: Stoichiometry Lab Oct. The purpose of this lab is to learn how to separate individual components from a mixture through decantation, filtration, distillation, and crystallization. What will you learn after completing the lab? Next isolation of the product was conducted by crystallizing the flask in an ice bath 10 minutes, followed by vacuum filtration, using cold water to wash the solution from the solid. To this was added 1.

Melting point was again taken 129°C as well as the weight 4. Acetic acid, Acid anhydride, Carboxylic acid 907 Words 3 Pages Ronak Parikh U30682934 Experiment 2: Diels- Alder Reaction: Synthesis of cis-Norbornene-5,6-endo-dicaroboxylic anhydride Introduction: The main goal of this experiment is to perform a Diels- Alder reaction between 2,3-dimethyl-1,3-butadiene and maleic anhydride, identify the product and hydrolyze to form the dicarboxylic acid. This type of reaction was named for Otto Diels and Kurt Alder who were the first to investigate this reaction Weldegirma, 2012. Acetic acid, Acid anhydride, Carboxylic acid 2440 Words 11 Pages anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. Since it did this very fast, it created lots and lots of bubbles. Like all catalysts, enzymes work.
