happens nucleophile reacts, that is and electron pair donor, while the reaction releases this make electrophile as the receptor [2]. These alkyl halides will be prepare from alcohol while reacting with halides, this mechanism support the substitution of alcohols [3]. A “First order of Nucleophilic substitution” of SN1, a weak nucleophile, which is unimolecular, a reaction that occurs step by step. The solvent that is favored by SN1 is polar protic [4]. SN2,
SN2 reactions are described as bimolecular nucleophilic substitution reactions that occur in one concerted step without the formation of a carbocation intermediate. These reactions are performed most effectively in polar aprotic solvents such as acetone. The steric hindrance presented in the substrate is considered the most important factor due to the fact that the more steric hindrance there is around the halide, the harder it is for it to leave. The collected data for the SN2 reactions support
nucleophile substitution reaction of converting 1-butanol (an alcohol) to 1-bromobutane (an alkyl halide). There are two types of substitution mechanisms that could be used, SN1 and SN2. SN1 mechanisms take place in two steps. The first rate-determining step is the ionization of the molecule. This mechanism is called unimolecular because its rate is only dependent on the concentration of the leaving group. The second step is the fast, exothermic nucleophile addition. In an SN2 reaction the leaving group
Analyzing the Products of Substitution Reactions with Alcoholic Compounds Adam Schroeder, Jessica Vecera, Brandon Guth Department of Chemistry and Chemical Biology, IUPUI, 402 N. Blackford St., Indianapolis, IN 46202 Three different substitution reactions were completed using different alcoholic compounds. Substitution reactions can either be Sn1 or Sn2 depending on the reactive properties of the reactants and catalysts. The reactive properties are also dependent upon the shape and whether
substitution reactions, and whether the reaction used an SN1 or SN2 mechanism. The structure of the starting alcohol determined the mechanistic pathway of the substitution reaction. Reaction 1 involved the substitution of a primary alcohol which produced one primary alkyl-halide via SN2 reaction. Reactions 2 and 3 began with a secondary alcohol, forming two products as the result of direct substitution and/or a hydride shift, via SN1 reaction. Reaction 2 formed two secondary alkyl-halides, and Reaction 3 formed
Purpose/Introduction: In this experiment, four elimination reactions were compared and contrasted under acidic (H2SO4) and basic (KOC(CO3)3) conditions. The acid-catalyzed dehydration was done on 2-butanol and 1-butanol; a 2ᵒ and 1ᵒ alcohol, respectively. The base-induced dehydrobromination was performed on 2-bromobutane and 1-bromobutane; isomeric halides. The stereochemistry and regiochemistry of the four reactions were analyzed by gas chromatography (GC) to determine product distribution (assuming
halides did react with the 1% ethanolic silver nitrate solution and which ones did not react. Through the evaluation of the precipitate, 2-chloro-2-methylpropane reacted instantly with the silver nitrate solution. This reaction occurred instantaneously due to the fact that SN1 reactions favor steric hindrance and the leaving group, chlorine, was a tertiary substrate. On the other hand, the two substrates that had secondary leaving groups were 2-chlorobutane and 2-bromobutane. When 2-bromobutane was
The better leaving group is Bromine. From the SN1 reactions, all alkyl bromides, with the exception of Bromobenzene, produced precipitates at room temperature. Although only the first tube in the SN2 reactions produced precipitate at room temperature, the back side attack happened where expected. It is notable, that in the SN¬2 reaction, eventually all alkyl bromides produced precipitate still with the exception prior. Chlorine as a leaving group has a higher activation energy. First observing the

In this experiment it is only focused on substitution reactions. “In a substitution reaction, an electron-rich species donates a pair of electrons to an electron poor species which forms a new product and a new base” (2). There are multiple types off substitution reactions and they are
and study of the reaction rates of chemical reactions. These reaction rates involve the pace or rate at which a reaction progresses. Many specific conditions can affect the reaction rate value; furthermore, the factors include the concentration of the reactants, the polarity of the solvent, and temperature1. The rate of reaction can be determined and studied using a rate law, an equation that correlates the rate with concentrations and a rate constant. This experiment’s reaction involving t-butyl
Dostoevsky’s Notes from Undergound - Reactions to an Overdeterministic Existence Some of the works cited are missing Dostoevsky presents his Notes from Undergound as the fragmented ramblings of an unnamed narrator. On the surface, the character’s narration appears disjointed and reaches no conclusive end ing until the author intercedes to end the book. However, a close examination of the underground man’s language reveals a progression in his collected ravings. After expressing dissatisfaction
Reactions to Patriarchal Oppression by Jane Eyre and Bertha Mason Missing Works Cited Jane Eyre and Bertha Mason are both oppressed by the British patriarchal system were men are the makers, interpreters, and enforcers of social and political rules. However, these two women differ greatly in the ways that they accept and cope with the reality of their place in society, and it is these differences that ultimately determine their fate. Jane Eyre follows the rules. Although she initially revolts
Reactions to Hooks’ Feminism is for Everybody I am not a feminist simply because I was raised in a feminist household. I am not a feminist because I am an independent, educated woman. I am not a feminist because I am a bitter female, nor because I am a “woman scorned.” I am not a feminist because I hate men, nor because I am a lesbian nor because I like to listen to the Indigo Girls. To the contrary I love men and I am not a lesbian. While I agree with hooks that “feminism is a movement to end
"We are a peculiar people," Elder Bruce R. McConkie once said (McConkie 25). The Church of Jesus Christ of Latter-day Saints is one of a few "odd" Christian religions. Many of its practices have created much persecution and political reaction, polygamy being one of these. It created much social and political persecution of the Mormons. Most of this persecution had come from anti-polygamist Christians. This is ironic because the anti-polygamists believed in the Bible, but not polygamy, one of its

Reactions to Industrialism in Frankenstein and The Communist Manifesto The radical changes of the nineteenth century were unlike any the world had seen before. A sense of these changes were felt by all in many aspects; not just politically, but in social and cultural means as well. When Mary Shelley's Frankenstein was published in 1831, it was clear that many general elements of the romantic era were well reflected. Similarly, Karl Marx and Frederick Engels' The Communist Manifesto appeared
An investigation of neutralization reactions Aim Question : What is the effect of changing the concentration of an alkali, on the volume of acid needed to neutralise it, when acid is added to it? The plan is to use two acids (Hydrochloric & Sulphuric) and one alkali (Sodium Hydroxide). The reason I need to use two acids is; because the question applies to all acids and alkalis and to just use one of each would not enable me to come to a general conclusion. If there had been more
Characters' Reactions to Death in Riders to the Sea In "Riders to the Sea" several reactions to the death of Michael take place when each of the individual characters learn of the tragedy and express their grief. The first, which would most naturally occur, is for someone to become extremely pessimistic. The character Mauyra most obviously becomes pessimistic even while she is still not sure of the fate of her son. Even the idea of Bartley leaving to sell the horses makes her nervous, she’s
condition. The product concentration in this reaction can be determined by titration. The product concentration at different time intervals was recorded. The graph ln ([HCl]∞−[HCl]t) versus time was plotted in order to find the rate constant of the reaction. The rate constant was determined by obtaining the gradient of the graph. Aims: To determine the rate constant of a chemical reaction in different solvent mixtures. To observe and account for the change in reaction rates when different solvent system are
of part A was to determine the rate of the substitution reaction between 1-Chlorobutane and KOH. This information was obtained by using the titration method to record the concentration of KOH over a given amount of time. To start this procedure, 1-Chlorobutane was added to a round bottom flask, which was connected to a reflux apparatus. Once it was observed that reflux had started the KOH was added with EtOH; this is the start of the reaction. The aliquot was then titrated with 0.100 M HCl and the
