Organic reaction

Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol…

Debromination of trans-1, 2 –dibromocyclohexane Both the solvent and the byproduct of this reaction are easily recyclable substances.5 This correlates to another major principle of green chemistry: the use of renewable raw materials. Rather than forming unusable waste products, both substances can potentially be used as reagents in future experiment…

respiration and in secondly mitochondrie structure then Acetyl-Coa wich contains Production and possible fates then Krebs Cycle wich contains reactions and regulation and finally Glyoxylate cycle. For the general overwiew of cellular respiration we will talk about cellular respiration. Cellular respiration is an aerobic phase of catabolism in which organic fuel molecule are oxidi-zed to H2O and CO2.Cellular respiration occurs in three major stages. The stage one is Acetyl-CoA production with…

variable would be duration of blue glow (in seconds). The scientist began by researching the chemical. The scientist found that Luminol, or C8H7N3O2, is a chemical that exhibits chemiluminescence (the emission of light as the result of a chemical reaction), with a blue…

The mixture was stirred, and a white precipitate of dicyclohexyl urea (DCU) was created after 15–30 min. The reaction was monitored by thin layer chromatography (TLC). After approximately 6–8 h, the precipitate was filtered and the filtrate was evaporated to dryness. The resulting residue was dissolved in acetone, filtered to additional remove any DCU, and evaporated…

water vapour. In this atmosphere, hydrolysis and condensation takes place. Finally the films are hardened by a high temperature cycle to form transparent metal oxides. Any hydrolysable compound including halides or nitrates but preferably metallo-organics are suitable for this process. The important control parameters are the viscosity of the solution, the pulling speed and the firing temperature. The rate of heating also needs to be controlled to avoid cracking of the films. This technique…

infrared spectrum, located in the range 450-850 cm−1 are characteristic of a Ti-O-Ti symmetric stretching vibration mode [4] and observed maximum at around 500 cm-1 corresponding to the stretching vibration of Ti-O, which are formed during condensation reaction of sol-gel synthesis. The most significant vibrational bands of TiO2 appears in the range 647 cm−1 to 830 cm-1, correspond to TiO2 modes in the anatase phase and change in absorbance intensity with higher calcined temperatures indicate…

Personal Statement "How can I help?" is a simple question that we normally either dismiss or greet with lukewarm enthusiasm. In this question though, rests a core intention of trying to be part of the solution. It may not seem important, but the simplest of ideas, motivations or questions can begin most journeys, which is true in my case. I remember that as a young child of around 4 years old, I would sit on the counter next to the medicine cabinet and read the back of all the medicine bottles.…

The kinetics of the reaction between peroxomonosulphate with Lactic acid was studied in the presence of Mn(II) at alkaline pH. The reaction followed first order with respect to peroxomonosulphate. The rate of the reaction was studied under pseudo first order condition and found to increases with the [Mn(II)] and lactic acid. Thermodynamic parameters were calculated and reported. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted. Keywords: Alpha…

Recrystallization is a very effective way for organic chemists to isolate a solid product from a small amount of impurities but cannot be used for liquids. The crude acetanilide product and the recrystallized acetanilide were compared using melting point determination and the recrystallized product was then classified and checked for impurities by determination of IR and 1H NMR spectra. Results and Discussion For this lab, a nucleophilic acyl substitution reaction was carried out to synthesize…
