TA: Alekhya 6/15/15 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

Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this

In this experiment‚ the objective is to successfully perform an SN1 reaction to determine the reactivity of tert-butyl chloride‚ through the usage of sodium iodide/silver nitrate reagents and to synthesize tert-butyl chloride. The tert-butyl chloride was synthesized through the use of separation (aqueous and organic layers) and distillation. Tert-butyl chloride is the alkyl halide which is being synthesized throughout the course of the experiment. Alkyl halides are derived from alkanes. Once an alkane

Unit 4 E1 There are 4 main laws that underpin the provision of health‚ safety and secure environments for early years settings. The Health And Safety act 1974 is one of these. This act states that buildings should be in good condition and they should be designed for the safety of the users. The buildings and its surroundings should be clean and safe‚ if any equipment is used it must be used safely and stored safely. Health and safety must be promoted to children. This law was put in place to

Marta Gebregziabher Discussion and Conclusion: Addition reaction of Alkenes: Bromination of (E)-Stilbene 1. Addition reaction is a reaction that involved two molecules that combine to make a larger product. Addition reaction has two main types‚ electrophilic addition and nucleophilic addition. An electrophilic reaction is when the pi bond of a molecule is removed to make two covalent bonds that are bonded to two new molecules. A nucleophillic addition is a reaction that removed the pi bond

Results and Discussion for Kinetic Study of Sn1 Solvolysis The Kinetic Study of Sn1 Solvolysis experiment was performed to find the kinetic rate constant and show how a change in polarity of the solvents can actually affect and determine the kinetic rate constant of a solvolysis reaction. A 50/50 mixture and a 60/40 mixture of water and ethanol was used and NaOH was added drop by drop to form HCl‚ which turned the solution green showing it was changing. This was when the time was recorded. By doing

Preparation and SN1 Reactivity of 2-Bromobutane Whitney Bellido Department of Chemistry‚ Illinois State University‚ Normal‚ IL 61790-4160 Submitted: April 4th‚ 2013 Introduction The overall goal of this experiment is to understand and be familiar of SN1 reactivity. We also learned how to prepare 2-Bromobutane by learning how to distill and extract this product from its organic layer. Finally‚ another goal was to specifically understand the relative reactivity of alkyl halides under SN1 conditions
