Sn2 Reaction

Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However, they are a poor leaving group the OH group is a problem in nucleophilic substitution, this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction, to see how a primary alky halide...

Reaction Iodoethane with Saccharin, an Ambident Nucleophile

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...

+ R'X R O R' + NaX     Ar O Na + RX Ar O R + NaX Involves a nucleophilic substitution reaction. Halide ion is displaced by the alkoxide or phenoxide ion. Gives best results when 1o alkyl halides are used. Mechanism is SN2.  Alkoxides may be prepared by reacting an alcohol with NaH or by reacting an alcohol with Na metal.  Phenoxides may be prepared by reaction of phenols with NaOH ROH + NaH ROH + Na ArOH + NaOH RO Na - - + + H2 RO Na + + 1/2...

1 SN2 Reaction, Ionic Liquid (Group – hood) Background Reading Solomons and Fryhle Chapter 6 (Substitution/Elimination Reactions) Techniques: Weights and Measures, Reflux, Liquid-Liquid Extraction, Distillation. Introduction The SN2 reaction is a bimolecular nucleophilic substitution reaction where the nucleophile (a molecule with a free pair of electrons) reacts with an alkyl halide and replaces the halogen (for more details see Solomons and Fryle, Chapter 6). The nucleophile approaches...

Rxn of Iodoethane with Sodium Saccharin

Title: Reaction of Iodoethane with Sodium Saccharin- Ambient Nucleophile Dates Performed: February 21 + 28, 2013 Date Submitted: March 14, 2013 Abstract: The product ratio of N-ethylsaccharin to O-ethylsaccharin that occurred due to alkylation with iodoethane at 80 oC was determined to be 81.5% to 18.5%, respectively, based on an analysis of the 1H NMR spectrum that was collected. The melting point range of 87.8-94.7 oC also indicated that the mixture was largely composed of N-ethylsaccharin...

The SN2 Reaction Requires Three Qualiti

The SN2 reaction requires three qualities: a strong nucleophile, a good, unhindered leaving group, and a polar, aprotic solvent. For our reaction, we have all three bases covered. The nucleophile is an alkoxide, a deprotonated alcohol. Technically, because our alcohol is a phenol, the conjugate base is called a phenoxide. Phenol itself has a pKa of about 10, but our alcohol has more resonance opportunities, so the pKa is down around 8. This is sufficiently acidic for use of weak base like K2CO3...

SN2 reaction lab

Introduction: Nucleophillic substitution is one of the most studied reactions in organic chemistry. In class, we are learning about two of these cases: SN1 and SN2. Many other reactions in this class proceed by mechanisms that are best described as somewhat between the two extremes. The SN2 reaction occurs in a single step. The nucleophile simultaneously attaches to the substrate as the leaving group leaves. The reaction displays second-order kinetics; its rate is proportional to the concentrations...

Reac 714 Studying Sn1 and Sn2 Reactions: Nucleophilic Substitution at Saturated Carbon

REAC 714 Studying SN1 and SN2 Reactions: Nucleophilic Substitution at Saturated Carbon Date of Experiment: February 6, 2008 Objective: The objective of this laboratory experiment is to study both SN1 and SN2 reactions. The first part of the lab focuses on synthesizing 1-bromobutane from 1-butanol by using an SN2 mechanism. The obtained product will then be analyzed using infrared spectroscopy and refractive index. The second part of the lab concentrates on how different factors influence...

Sn1 reaction

Reminder: These notes are meant to supplement, not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment, t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction...

Competing nucleophiles

1-butanol is SN2, and bromide is a better nucleophile. The first reason is that the substrate is a primary alcohol. The SN2 reaction is the nucleophilic attack of a central atom which kicks out the leaving group. A primary alcohol only has hydrogens plus the leaving group attached to the central carbon. Since the hydrogens do not hinder the nucleophilic attack, SN2 reaction is favored. The second reason is that bromide is a better nucleophile. Nucleophlicity is an essential factor in SN2 mechanism...
