The SN2 Reaction: Factors Affecting SN2 Reaction.
Introduction
In the substitution reactions, the leaving group from the substrate is replaced with the nucleophile. Because of the nucleophile it is called nucleophilic substitution. The lone pair of electrons, present on the nucleophile is used to create a new bond with the carbon atom, from which the leaving group was separated. There are two different mechanisms of nucleophilic substitution: SN1 and SN2. The difference between the two depends on how the reaction occurs.
The SN1 reaction is unimolecular, meaning that the rate of the reaction depends on the concentration of the substrate only. The concentration of the nucleophile does not affect the rate of the reaction. In SN1 reaction, the leaving group leaves first. Forming a carbocation, then nucleophile forms the bond with the positively charged carbon. Therefore the reaction consists of two steps. …show more content…
Since a lot substances can be received a product of an SN2 reaction, the mechanism is widely used.

    An SN1 reaction is a nucleophilic substitution reaction where the rate determining step of the reaction is unimolecular, thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile. This relationship holds for situations where the amount of nucleophile is much greater than that of the carbocation intermediate. The reaction (which involves a carbocation intermediate) is commonly seen in reactions of secondary or tertiary alkyl halides under strongly basic conditions or, under strongly acidic conditions (in this case strongly acidic conditions), with secondary or tertiary alcohols. In this reaction, the alcohol will be protonated by the hydrochloric acid. H2O will then “leave” the molecule in the rate-determining step, forming a relatively stable tertiary carbocation (which is highly substituted). The chloride ion, acting as a Lewis base will donate a pair of electrons to the carbocation (acting as a Lewis acid) forming the…

    Reaction Iodoethane with Saccharin, an Ambident Nucleophile

    Reaction Iodoethane with Saccharin, an Ambident Nucleophile

    In this experiment, we alkylate sodium saccharin to N-ethylsaccharin with iodoethane in an aprotic solvent N,N dimethylformamide. Nucleophiles in this experiment will react better in an aprotic solvent. Aprotic solvents have dipoles due to its polar bonds but they do not have H atoms that can be donated into a H-bond. The anions which are the O- and N- of sodium saccharin are not solvated therefore are “naked” and the reaction is not inhibited and preceded in an accelerated rate. The reaction was an SN2 reaction. Since the Oxygen and Nitrogen are more electronegative than the carbon on which they’re attached electrons are pulled towards O- and N- attracting the ethane from Iodoethane. Iodine being more electronegative breaks off from ethane and joins the Na+. Since, the Oxygen of sodium saccharin is more electronegative than the nitrogen therefore this gives oxygen a higher partial negative charge therefore an attack on Oxygen will give a product that is formed faster; this can be called a kinetic product. The transition state energy is lower than a product formation by thermodynamic control. At thermal equilibrium at 80°C a more stable product is form from a higher transitional state energy. The nucleophiles in the molecule sodium saccharin are O- and N- and the major product formed depending on which oh the nucleophile was attacked most in the reaction. Nucleophilic attack by nitrogen will yield N-ethylsaccharin and nucleophilic attach by oxygen will yield O-ethylsaccharin. “N-saccharin is more stable than O- ethylsaccharin because the Ethyl group is attached to the Nitrogen giving the same spacial configuration for the five membered ring (which is flat or planar).” (Richard y.a.). The carbonyl carbon is sp2 and flat. This has little ring strain and is stable. The first bond between carbon and oxygen in a carbonyl group is created by overlapping an sp2 hybrid orbital from carbon with an sp2 hybrid orbital from oxygen (sigma bond). The second bond…

    “A nucleophile is any neutral or uncharged molecule with an unshared pair of electrons. In the substitution reaction, the nucleophile donates an electron pair to the substrate, leading to the formation of a new bond to the nucleophile, while breaking the existing bond to the leaving group” (Solomons and Fryhle 99-102). The two types of nucleophilic substitution reactions, SN1 and SN2, are identified based on whether the different steps occur simultaneously (SN1) or in two separate steps (SN2). To synthesize the t-butyl chloride, the t-butyl alcohol goes through an SN1 reaction. Also, the nature of the solvent can affect which substitution reaction will occur. Polar protic solvents typically favor SN1 reactions. This is because the SN1 mechanism is carried out in two steps and the polar protic solvent produces both a cation and an anion which are capable of stabilizing the charges on the ions formed during the reaction. Because an SN2 reaction occurs in one step, this is unfavorable; however, the SN2 reactions tend to favor polar aprotic solvents. Another factor affecting the type of substitution reaction is the nature of the leaving group. Since the SN1 reactions occur in one step,…

    Title: Nucleophillic Substitution Reaction

    Bromocyclopentane reacts under SN1 and SN2, but it shows a faster reaction in AgNO3/ethanol reagent, that is SN1. This is because bromocyclopentane is secondary bromine, and have bigger steric strain, since it is a cyclic compound. The bigger steric in a molecule, the harder it is for the nucleophile to attack the leaving group (-Br) from the opposite sides, therefore, SN2 reaction is slower than SN1 for bromocyclopentane. From this reaction, precipitation occurs to give out AgBr in ethanol and NaBr in acetone.…

    Nitrating Acetanilide and Methyl Benzoate: Electrophilic Aromatic Substitution

    An electrophilic aromatic substitution reaction is the attack of an electrophile on an aromatic ring substituting for a proton. This reaction allows for the introduction of other functional groups onto the aromatic ring. The electrophile attacks the aromatic ring at the aliphatic position removing two electrons destabilizing the aromatic ring, but creating a resonance-stabilized carbocation called a sigma complex (arenium ion). Then the aliphatic proton is lost to give the substitution product.…

    E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group, which consists of a weak base, leaves an organic compound, leaving an intermediate carbocation. In the second step, a carbon on the organic compound is deprotonated by a Lewis base, resulting in the formation of an alkene. The dehydration reactions of 1- and 2-Butanol with sulfuric acid occur through an E1 mechanism, so they follow the steps previously…

    Rxn Of Iodoethane With SodiumSaccharin

    The solvent used in this reaction is very important for determining the rate of nucleophilic substitution reaction. Polar protic solvents such as water and ethanol result in bulky solvation shells around the charged nucleophile; this is what reduces its nucleophilic strength. The result is a slower reaction. Polar aprotic solvents do not solvate the nucleophile very strongly, this results in an attack on the substrate. Therefore, polar aprotic solvents accelerate the rates of reaction, especially SN2 reactions, where the strength of the nucleophile determines the rate of reaction.…

    Single Replacement Reaction Essay

    Chemistry is a branch of science that plays a role in many aspects of life, and one of its goals is to study the interactions caused by the combination of substances. The combination of substances often causes reactions, and one of the main groups of reactions is the single-replacement reaction. In Amrita University’s explanation of single replacement reactions, a single replacement reaction is defined as a “chemical reaction in which a more reactive element displaces a less reactive element from its compound.” The general formula for single displacement reaction is: AB + C  A + BC.…
