  • Bromination Lab Report

    785 Words  | 4 Pages

    hydrogen atom of benzene or benzene derivative is replaced by bromine due to an electrophilic attack on the benzene ring. The purpose of this experiment is to undergo bromination reaction of acetanilide and aniline to form 4-bromoacetanilide and 2,4,6-tribromoaniline respectively. Since -NHCOCH3 of acetanilide and -NH2 of aniline are electron donating groups, they are ortho/para directors due to resonance stabilized structure. Even though the electron donating groups activate the benzene ring, their

    1022 Words  | 5 Pages

    Lab Report 10: Nitration of Bromobenzene Raekwon Filmore CM 244 Section 40 March 27, 2018 Introduction: For this experiment, nitration of bromobenzene was the focus of the lab. The benzene is an aromatic compound and when it reacts with wither a mixture of sulfuric acid or nitric acid creates what is known as a nitro group. The formation of the nitro group is possible because it is an electrophilic aromatic substitution reaction. The creation of the nitronium ion is shown below: The reaction

  • Glacial Acetic Acid Lab Report

    2323 Words  | 10 Pages

    Introduction: Benzopinacol can be prepared from benzophenone in presence of sun light (photochemically) using isopropanol as the reducing agent in presence of acetic acid. Acetic acid is added to prevent the cleavage of benzopinacol to benzophenone and benzhydrol by the alkali derived from the glass container used for the reaction. Benzopinacol obtained in the first experiment is converted to benzopinacolone by heating under reflux (5 minutes) with glacial acetic acid containing trace amount of iodine

  • The Anthraquinone Dye Experiment

    867 Words  | 4 Pages

    The anthraquinone dye experiment has the purpose to identify the anthraquinone dyes from unknown mixture by using thin layer chromatography (TLC) of the unknown fraction. An anthraquinone is an aromatic organic compound obtained by the oxidation of anthracene. To separate the compounds in the mixture, column chromatography and thin layer chromatography uses portioning of a sample between a stationary solid phase and a liquid mobile phase. As the stationary phase, they use either silica gel or alumina

  • Methanol Lab Report

    1257 Words  | 6 Pages

    In this experiment, extraction was used as a separation technique to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with opposite polarities are used to dissolve different parts of the solute with different polarities, so they form two distinct liquid layers. In this experiment, methanol, an organic solvent, and an aqueous solution were used as the two immiscible solvents. The extraction solvent must also be capable of dissolving one of the mixture components

  • Friedel-Craft Acylation Simulation Lab Report

    629 Words  | 3 Pages

    In the synthesized Friedel-Craft acylation reaction mechanism, anisole (methoxybenzene) is the nucleophile. The double bond on the nucleophile attacks the electrophile acetyl. The acetyl compound is then bound to the anisole in the para position, which created the product p-methoxyacetophenone. Since anisole is an activator (electron donor), the acetyl could have bound in either the ortho or para position (or in the meta position, but it is not as likely). However, the reason that acetyl was not

  • Recrystallization Of Acetanilide Essay

    920 Words  | 4 Pages

    Introduction The purpose of this experiment was to purify acetanilide that was contaminated with relatively small amounts of impurities using recrystallization. The success of recrystallization was dependent on a suitable solvent being chosen and proper recrystallization technique being carried out. The solvent chosen had to have a different polarity than that of the molecule of interest. The technique used was dependent on the solubility of the solvent at higher temperature and the

    In this experiment, extraction was used as a separation technique to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with different polarities are used to dissolve and separate different solute components, so they form two distinct liquid layers. In this experiment, ethyl acetate, an organic solvent, and an aqueous solution, were used as the two immiscible solvents. The extraction solvent must be capable of dissolving one of the mixture components, without irreversibly

    The Citric Acid Cycle/ Kerbs Cycle/ TCA The Citric acid cycle is important as anaerobic glycolysis can only harvest a fraction of the energy from glucose. In the citric acid cycle there is aerobic respiration of pyruvate from step ten in glycolysis to C02 and H2O. This oxidation of pyruvate can greater a higher yield of ATP. The citric acid cycle occurs in the mitochondria where ten ATP is produced. The main purpose of the citric acid cycle is to harvest electrons from the citric acid cycle and

  • How Einstein Changed The World

    705 Words  | 3 Pages

    Albert Einstein is known to be responsible for a scientific discovery that changed the world forever. Energy is equal to mass multiplied by the speed of light squared. This equation has changed the world in many ways by teaching us how mass and energy are related as well as mass is converted to total energy. It all began in the early 1800s when scientists thought of mostly forces instead of energy. This movie summarized the story of how the equation E= mc^2 was created, along with many other scientific

  • Nitration Of Methyl Benzene Essay

    907 Words  | 4 Pages

    presented in Figure 1. Figure 1: Benzene can only undergo substitution reactions that are called electrophilic aromatic substitution reactions. Given that benzene rings are used commonly in the production of many organic compounds, the capability to make substitutions to benzene is critical. This can be accomplished by the use of Electrophilic Aromatic Substitution (EAS) as Nucleophilic Aromatic Substitution (NAS) is not possible because of the electron-rich benzene ring, which does not have substituents
