SN2 reaction

an SN1 reaction. The SN1 reaction took place with a polar protic solvent taking the place of the leaving group (alcohol) and creating a new replacement bond with the carbocation to form a tertiary chloride structure. The product was then tested for this structure by reacting it with two substances: sodium iodide and silver nitrate. These tests were to demonstrate that if the product obtained through experimentation was indeed a tertiary structure, it would react readily via an SN1 reaction with…

Afghanistan: There were many challenges in the military but I am choosing to write about one scenario that made me realize what type of person I am. Even though I had struggle all through school, I was surprisingly good at being a Marine. Once I finished my first year in the military my parents grew to be pretty comfortable with the idea of me being in the corps. I think it is because they saw that I was finally growing up. In the Marine Corps they do not care about excuses and they definitely…

Examining Substitution Reactions of Several Alcohol-Containing Compounds Several Experiments were performed using substitutions reactions with hydrogen halides. These results and favor methods or pathways for the several alcohols were observed and will be discussed. Introduction for all the material Scheme 1. Substitution of 3-(m-tolyl)propan-1-ol to form 1-(3-bromopropyl )-3-methylbenzene. Aromatic materials used in this reaction has high boiling point thus the reaction was heated…

that the nucleophile needed to get into the organic phase in order to react with the electrophile. The reaction would have proceeded without this addition although it would have been a very slow reaction. This is because the addition of tetrabutylammonium bromide simply speeds up the reaction and is not necessary for the reaction to occur. First, the p-cresol was deprotonated and then an SN2 reaction occurred. The yield obtained reflects how efficiently…

According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…

Human factors to be considered include ergonomics, fit, ground reaction force, weight, durability, stability, and cushioning. Ergonomics dictates good posture. In order to maintain good posture, referred to as 'neutral posture ', the muscles of the body must be in balance to support an aligned spine13. The design of this shoe must take ergonomics, perception, quality control, and biomechanics into account. Fashion has been a deciding factor in the shoe industry over the last decade.14 For…

Dissolving can be either endothermic or exothermic. Endothermic reactions happen when the energy given out when bonds are broken, is greater than the energy given out when bonds are made. As more energy is used and taken in, the surroundings become colder. Dissolving is exothermic when energy is given out to its surroundings. In an exothermic reaction bonds are being made. The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to get warmer.…

Enzymes speed up the rates of most biochemical reactions by helping reactants interact with each other. Since enzymes are highly specific for a specific reaction, they only catalyze one or a few types of reaction. One of important enzymes in human body and many other animals is amylase that hydrolyzes starch, a major part of human diet for many people in the world. There is a variety…

Concentration on Reaction Rates and Pressure Background - While conducting the Enzyme Lab, students used enzymes as catalysts in order to speed up the reaction processes involved in several tests. Enzymes are substances produced by living organisms that act as a catalyst, while a catalyst is a substance that increases the rate of the chemical reaction. Furthermore, varying amounts of pH and enzymes were added to the mixture in order to determine the substance’s rate of reaction. When the…

Purpose To investigate the effect of temperature on the rate of the thiosulphate reaction. Hypothesis If the temperature increases, then the rate of the thiosulphate reaction will also increase. Variables Independent variable: Temperature change in each experiment, which will be varied by increasing the temperature by 10°C each time. Dependent Variable: Rate of reaction, which will be measured by measuring the time taken for the cross to not be visible. Constants: Concentration of HCl and…
