Nucleophilic substitution

Nucleophilic Substitution Samantha Gutierrez Nucleophilic Substitution Introduction: The purpose of this lab is to investigate how different factors affect the rate of SN1 and SN2 reactions. SN2 reactions proceed via a one step mechanism in which the incoming nucleophile attacks the electrophilic carbon center from the opposite side of the leaving group. This reaction mechanism implies that the stereochemistry of a chiral center will be inverted. SN1 reactions proceed via two steps, slow

A unimolecular nucleophilic substitution of t-amyl alcohol should be done to convert into t-amyl chloride through extraction and simple distillation. A concentrated hydrochloric acid was added to the reactant to force the reaction to take place. Infrared spectroscopy was utilized to verify that the contents of the tert-amyl chloride should be different from the starting material. In this reaction, a rate-determining step should occur through the ionization between carbon and –OH bond to form an

Lab Report 9: SN1 and SN2 Mechanisms: Nucleophilic Substitution Raekwon Filmore CM 244 Section 40 March 27, 2018 Introduction: For this week’s experiment, involved nucleophilic substitution of SN1 and SN2 reactions. On two separate days, SN2 was done first followed by SN1 being done in the next lab. The substitution of one group from a saturated sp3 hybridized carbon atom is typically a reaction that is used to interconvert different functional groups. In this reaction in particular, nucleophiles

The nucleophilic substitution SN1/SN2 typically occur in a competitive regime. There are various conditions that define the predominant reaction mechanism taking place. Since SN1 leads to the racemic mixture, SN2 is more popular in asymmetric organic synthesis. So, detailed computational studies of model SN2 reactions have been carried out during the last three decades[2-6, 9]. The influence of solvation of the nucleophile with several common solvents on the rate constant of the reactions F-(Sn)

The Diel-Alder/Nucleophilic Acyl Substitution Cascade Reaction Introduction The Diels-Alder reaction was discovered and named after the Nobel Prize winning scientists Kurt Alder and Otto Diels in 1928. Such a reaction occurs when a diene with two adjacent double bonds is mixed with a dienophile consisting of a double bond in order to create a cyclohexene. The diene must be in the s-cis conformation in order for the electron transfer to engage correctly. If the diene in question is in s-trans conformation

Title: Relativities of Alkyl Halides in Nucleophilic Substitution Reactions Introduction: The purpose of this lab was to perform a comparison of relative reactivities of various alkyl halides with two different reagents, sodium iodine in acetone and silver nitrate in ethanol. (Below are the reaction equations). We used different substrates, which were primary, secondary, and tertiary. These substrates included 2-bromobutane, 2-bromo-2-methylpropane, 1-bromobutane ∞-Bromotoluene, bromobenzene

Nucleophilic aliphatic substitution is the substitution of one functional group for another functional group. The substitution is made at a saturated carbon atom. A saturated carbon is a carbon atom that is sp3-hybridized. For a compound to be considered a nucleophile they must possess certain properties. Nucleophiles must contain at least one pair of non-bonding electrons and be neutral or have a negative charge. Through nucleophilic substitution the non-bonding electrons are donated to the

Blackford St., Indianapolis, IN 46202 otrusty@indiana.edu The three reactions investigated through various experimental testing contain an alcohol leaving group positioned on primary or secondary carbons. The substitution method (SN1 or SN2) used in the

Experiment #1 Nucleophilic Aromatic Substitution of 2,4-dinitrochlorobenze Name: Anouk Deck-Leger Student I.D: 9380868 Date performed: September 13th, 2010 Due Date: September 20th, 2010 Introduction: The company DNCB produces large amounts of 2,4-dinitrochlorobenzene and they sell this product to treat against warts and severe and chronic hair loss. It can also be used as an alternative treatment for HIV. The supervisor notices an excess amount of m-aminobenzoic acid stored away which
