Conclusion Of Organic Chemistry Lab

Decent Essays
The organic chemistry lab this semester was a very interesting class, in that it provided further insight as to how chemical reactions occur as well as examined how drugs and different compounds can be made from those reactions. Additionally, this class more thoroughly exposed me to the different types of machines that organic chemists use to determine the structure and purity of certain compounds. Almost every experiment performed in the lab this semester included the use of IR, NMR, and GC-MS to determine the structure of the reactants and products. Furthermore, the use of those machines also gave me insight as to how difficult it is to produce a pure compound, in that occasionally some of my products would be missing some substituents.

In the experiment, we converted some unknown starting material to some unknown product. Then in order to determine what the structures of these two unknown molecules were we ran, collected, and interpreted IR, NMR, and GC-MS. We had to apply the rule of 13 in order to determine the molecular formulas of the unknowns as well as determine the degrees of unsaturation in the compound. Then from that data we were tasked with determining how the starting material became the product via an arrow pushing mechanism. The mechanism that was involved was a fairly basic one, but one that reinforces some of the basic ideas in organic chemistry. The mechanism started off with the protonation of a hydroxyl group from an acid, then that group leaving the molecule as water. Next, was a 1,2-methyl shift which caused a very stable carbocation to form. However, the other hydroxyl group on the molecule, specifically the oxygen atom, donated its electrons to form a pi bond to the carbocation, thus forming a ketone with a positive charge. Then the water molecules deprotonated that ketone and restored acid catalyst. Thus many of the basic concepts and reactions were able to be deduced from this …show more content…
So much waste can result from certain types of reactions and experiments, so it was interesting to see how experiments can be made greener, and thus leave a smaller environmental footprint, “On college campuses, the waste generally gets transported to a central waste-handling location, where it is packed or combined for transport to a hazardous-waste incinerator”(1). Thus, if more experiments were greener, there would be less need to incinerate the waste resulting in wasted power as well as environmental pollutants. Specifically, in this experiment, a Diels-Alder reaction was able to be conducted with a minimal amount of byproduct or waste, thus leading to a more environmentally friendly experiment. Additionally, the reaction was able to take place at room temperature, thus preventing the wasting of electricity in order to heat up the reactants on a hot

    In my years of high school, I took all honors classes and tried to challenge myself as much as possible. This summer, when I received my schedule, I saw organic chemistry was one of my classes. Many people told me that this class was impossible, so I went into school with my mind set on switching out immediately. Alternatively, I decided to try it out and, to my surprise, I actually…

    “Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total there are five (5) chemical reactions.…

    The first objective of Lab 4 is to use structure activity relationships to predict the properties of an acid and the potency of hallucinogenic compounds. The overall goal of the laboratory is to examine quantitative structure activity relationships (QSAR) in a system that is either chemical or biochemical. The lab is divided into two parts; predicting the acidity of an organic acid, and predicting the hallucinogenicity of derivatives of mescaline. The materials of this lab for both part 1 and part 2 are small training sets, which are groups of similar chemicals with known biological activity, a computer to graph the data that is recorded in the tables, the internet resource MiLogP to generate LogP data, and computational programs that will…

    A possible chemical reason that this experiment yielded less than 100% cyclohexanone was due to the spontaneous decomposition of sodium hypochlorite, 2NaOCl = 2NaCl + O2, which decreased the amount of reactant present in the initial reaction when hypochlorous acid was formed, which was the oxidizing agent required to oxidize cyclohexanol into cyclohexanone. Sodium hypochlorite decomposed into O2 and NaCl due to a multitude of factors such as exposure to high temperatures, prolonged storage time or sunlight exposure. If a large enough quantity of the sodium hypochlorite was decomposed to limit the reaction that produced hypochlorous acid, the quantity of cyclohexanone produced may be affected. This would have resulted in a decrease in the production…

    In Experiment 12B we used an umpolung reagent in an umpolung synthesis to synthesize benzoin from benzaldehyde. Umpolung synthesis is a synthetic approach that allows us to switch the identity of a reacting species. For example, the normal chemical reactivity of a nucleophile can be switched to one of an electrophilic compound. Two common agents are cyanide and thiamine (Vitamin B). The mechanisms for both agents are the same.…

    Introduction In this experiment, isopentyl acetate was prepared by the direct esterification of acetic acid with isopentyl alcohol, which is an equilibrium that results in a shift in favor of the product by using one of the starting materials in excess. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. Esters are found in numerous natural products, including fruits, flowers, and spices. Carboxyllic esters contribute to the flavor of products; therefore, esters are often found in artificial flavorings.…

    In this equation, x and y denotes the number of moles of RE and Mn atoms per formula unit of the structure, respectively. The RE and Mn represent the theoretical magnetic moment of trivalent free RE3+ ions and divalent Mn2+ ions respectively. The experimental values of total magnetic moments were found to be smaller than the calculated values (Table xyz). The crystal field effects can lead to lower value of magnetic moments for RE3+ ions in these compositions as compared to free RE3+ ions, which in turn could lower the total magnetic moment of these compositions. This discrepancy in the total magnetic moment values could also be due to the presence of secondary phases in these samples.…

    In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds.…

    Personal Statement I am writing this Personal Statement in support of my application to study for a Master’s degree in Biochemistry at the California State University Sacramento. My interest in Biochemistry has always been a real world interest, and my desire to study Biochemistry at the Master’s level is likewise fueled by the imperativeness of the subject and the crucial role it plays in our everyday lives. The part I want to play as a Biochemist – in bringing to the world's attention the implications of current health practices, various diseases, and living processes – is in my point of view, the essence of biochemical studies. Society has continued solving challenges, seemingly insurmountable and perhaps more pressing than we have ever faced – I strive to be at the forefront of the “solution-finding” as a research scientist.…

    The scientific method is a procedure that is used by scientists now and in the past, dating back to the seventeenth century. The scientific method consists of observation, measurement, and experiment, and the creation and testing of hypotheses. There are several steps and different components to the scientific method that will (hopefully) answer the scientists’ questions, by the completion of the experiment. There are countless different reasons as to why a scientist would use the scientific method, but one area of research that is focused on is, biology. Biologists seek to find the answers to further and better understand the processes that occur in living systems.…

    Benzocaine was synthesized from p-toluidine in a four step synthesis. Each intermediate product, including N-acetyl-p-toluidine, p-acetamidobenzoic acid, and p-aminobenzoic acid, was checked for yield, presence, and purity through weighing, taking IR and NMR spectrums, and determining the melting point. Thin Layer Chromatography was used to ensure the completion of the final reaction from p-aminobenzoic acid to benzocaine. The yield of the first step from p-toluidine to N-acetyl-p-toluidine was 91.9%. The yield of the second step from N-acetyl-p-toluidine to p-acetamidobenzoic acid was 49.85% The yield of the third step from p-acetamidobenzoic acid to p-aminobenzoic acid was 32.49%, which was not enough to continue so some product was borrowed…
