Nucleophilic Substitution Reaction In Sn2
SN means nucleophilic substitution reaction (S= substitution N= nucleophilic).
It is a reaction between a nucleophile (gives electrons away) and an electrophile (attract electrons). A leaving group on the electrophile is needed for this reaction to happen.
There are two types of nucleophilic substitution reactions: SN1 and SN2.
In SN1 the 1 means that there is one species reacting in the lowest step and this reaction is a step by step process; in SN2, the 2 means that there are two species reacting in the lowest step and this reaction happens at the same step.
In SN1, first a carbocation will form and then the nucleophile will attack it. The nucleophile can attack from both sides (backside and front side) as this happens in two steps. In

    When the electron has reached photosystem I it is attached to a special pair of chlorophyll in the reaction center called p700. Light energy is then absorbed by pigments which are passed on to the reaction center , the electron which is in p700 is then boosted to a high energy level which is then transferred to a acceptor molecule. As the special pairs of electron is missing it is then replaced by a new one from photosystem II.…

    Keq Reaction Lab Report

    The Keq, ratio of the concentrations of product to reactant, reveals the amount of product formed depending on the number of reactant accessible. The first reaction A+B↔C+D(Keq= 3.9X10-12) favored reactant because Keq is less than 1, meaning more reactants than product is present. Thus, the reaction displays reactant(blue).This is an extreme case where the reaction does not proceed forward readily. For second reaction I+J↔K+L(Keq=8.7x10-1), reactant(blue) is favored, but shows adequate amount of product(yellow) because its Keq is closer to 1. In S+T↔U+V(Keq=5.2x1018), another extreme case, Keq is greater than 1, so less reactant is present. Consequently, the reaction is mostly complete, favoring product(yellow) side. If a reaction either reach…

    “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,…

    Double Replacement Reactions

    Determine whether an ionic double replacement reaction has occurred.If I place different amounts of ionic solutions in a well plate, then I will be able to determine which of the solutions has had an ionic double reaction placement because I will use the solubility rules to decide which product produced the solid precipitate.Place five drops of silver nitrate into well A1 through A4. Place five drops of Iron (III) Nitrate into rows B1 through B4. Place 5 drops of copper (III) nitrate into rows C1 through C4. Now you will place four different ionic solutions in each column 1 through 4. Place five drops of Potassium Iodide in column 1A, 1B and 1C. Place five drops of sodium sulfate in column 2A, 2B, and 2C. Place five drops of sodium hydroxide in column 3A, 3B, and 3C. Place five drops of sodium chloride in column 4A, 4B, and 4C. Record the color of a precipitate that has formed in the data table and “NR” if no precipitate has formed showing no sign of a reaction.Add a little water to each well and turn the well plate over on a paper towel. Throw the towel away and clean the plate. 1. H2CO3. 2. CaCl2 (aq), H2CO3 (s). 3. Sodium Carbonate aqueous plus hydrogen Chloride aqueous yields Sodium Chloride plus Hydrogen Carbonate. 4. Well…

    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…

    Preparation and Sn1 Reactivity of 2-Bromobutane

    To prepare the 2-Bromobutane you must fill a 100 mL round bottom flask with 20 mL of 12M sulfuric acid and 7.4 mL of 2-butanol. Then add 8.0 g of ammonium bromide along with a magnetic stir bar. Then attach the flask to the apparatus, which is mounted on a Thermowell over a stirrer and a condenser attached to it, along with the thermometer in the flask. Then the mixture was heated at 90oC then kept at the range of 90oC-100oC for 30 minutes. When that is completed add 20 mL of water into the flask to perform a simple distillation to collect the distillate in a graduated cylinder, keep doing this until there is no more 2-Bromobutane collected. Use a Pasteur pipette to draw off the organic layer to another container. Add the potassium carbonate to allow the liquid to dry by swirling it.…
