This lab will allows the comparison between elimination reactions under acidic and basic conditions through an analysis of two separate reactions: an acid-catalyzed dehydration of 1-butanol and 2-butanol using sulfuric acid and a dehydrobromination under basic conditions using potassium tert-butoxide of 1-bromobutane and 2-bromobutane. The products of all four reactions will be analyzed with gas chromatography‚ which separates organic compounds to see how each reaction’s product are formed under

In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser

Experiment 14: Preparation of 1-Bromobutane Goal: To prepare 1-Bromobutane by the SN2 reaction from 1-Butanol with Sodium Bromide and Sulfuric Acid. Mechanism: Procedure: 1. Place 27g of NaBr‚ 20mL of n-butyl alcohol‚ and 30mL of water into a 250mL round bottom flask. 2. Put the mixture in an ice-water batch and cool briefly‚ then slowly add 23 mL of conc H2SO4 while stirring with a magnetic stirrer. 3. Place a water-cooled condenser and heat the flask until the mixture boils while

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 the rate

Summary of Chapter 11 Material SN2 Reaction Substrate: NO SN2 ON A TERTIARY HALOALKANE!! order of reactivity is as follows: Methyl > 1 > 2 Sterically less hindered substrates have faster rates in SN2 Nucleophile: If the reacting atom is the same in a series‚ nucleophilicity parallels basicity (i.e. -OH > -OCH3 > -OCH2CH3 > H2O) For the halogens in GAS PHASE: F- > Cl- > Br- > IFor the halogens in SOLUTION: I- > Br- > Cl- > F- (due to solvation of nucleophile‚ rendering it inactive) Negatively

The objective of this lab was to prepare n-butyl bromide or n-bromobutane‚ which is derived from an alcohol and an acid. In this case‚ n-butyl alcohol and sulfuric acid were the reagents. There were two methods of distillation that was involved in this experiment. The first was by reflux distillation‚ which is used to speed up a chemical reaction without having the reactants/ products evaporate or explode. Data Table 1 indicates the amount of each reagents that was prepared for the reflux apparatus

Kaily Purtle 09-10-2012 Study of the Family Reaction Paper 1 In class we discussed Reading #4. This reading was about the “Super Mom”. We discussed our personally experiences along with readings. We talked about how stay at home mothers and working mothers get looked at by society and by their husbands. I will be writing my reaction paper on this topic because it is very interesting to me. The “Super Mom” is described in the White and Klein text as a “stroller in one hand‚ brief

People around the world have their own cultures that include religion‚ but also many people choose to believe or not believe in specific things. While culture might be tradition‚ religion might be choice. Culture and religion are similar and connected in various ways. Many different beliefs and views concerning social affairs‚ politics‚ and morality are affected

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
