Title: Competing Nucleophiles (Exp 24‚ pp 211-221‚ pp 808-823‚ pp 836-842) Purpose: The purpose of this experiment is to determine the nucleophilic strength of chloride and bromide ions as it reacts with 1-butanol (n-butyl) and 2-methyl-2-propanol (t-butyl alcohol) under SN1 and SN2 conditions. Method: 40 g of ice and approximately 30 ml of sulfuric acid is cautiously added to a 100 mL beaker respectively. Weigh 7.6 g of ammonium chloride and 14.0 g of ammonium bromide and place it in

Experiment 5- Competing Nucleophiles Table of results: Area (mm²) Percent composition 1-bromobutane 511 85.02% 1-chlorobutane 90 14.98% 2-bromobutane 432.25 78.63% 2-chlorobutane 117.5 21.37% 2-bromo-2-methylpropane 280 37.58% 2-chloro-2-methylpropane 465 62.42% Discussion: 1. In 1-butanol Base on the data table‚ 1-bromobutane dominated the composition of 85.02%‚ which indicates the conclusion that the mechanism for 1-butanol is SN2‚ and bromide is a better nucleophile
Premium Alcohol Nucleophile
Competitive Nucleophiles With 1-Butanol In this experiment you will determine the nucleophile strength of bromide ion vs. chloride ion in their reaction with 1-butanol in acidic solution. The reaction is shown below. The reagents are a convenient source of HBr and HCl. The reaction is an SN2 reaction with H2O as the leaving group and Cl- and Br- as the nucleophiles. The molar amounts of Cl - and Br- are equal‚ so the better nucleophile will lead to more product. You will analyze the amounts of 1-bromobutane

Competitive Nucleophiles Introduction: The purpose of this experiment was to compare the relative nucleophilicities of chloride ions and bromide ions in two different reactions. One reaction involved n-butyl alcohol and the other involved t-pentyl alcohol. We performed the reactions and compared the percentages of alkyl chloride and alkyl bromide in the product. To perform this experiment‚ we used methods including heating reaction mixture under reflux‚ extraction using a separatory funnel

very easy and forms a positively charged ammonium ion. As well as being a strong base‚ amines are also quite good nucleophiles. When the nitrogen is directly attached to one or two R groups is more nucleophillic than when directly attached to a hydrogen atom. The reason behind this is due to the electron donating ability of the alkyl group. However‚ the increasing strength of the nucleophile proves difficulty when added

Katie Smith April 11‚ 2013 Competitive Nucleophiles Introduction The purpose of this experiment was to compare the nucleophilicities of chloride and bromide ions toward the n-butyl and t-pentyl alcohols. We were able to analyze this by using refractometry to measure the amounts of alkyl chloride and alkyl bromide in each reaction. Experiment Scheme (Procedure A) To begin the experiment‚ we assembled a reflux apparatus in the fume hood with a 100 mL round bottom flask and a condenser

Competing Ideologies Thursday May 9th 2013 Following Confederation in 1867 and into the turn of the century Canada was divided among three competing ideologies. The first being Imperialism‚ a belief favoured by English speaking Canadians and the Conservative government‚ that strong British ties held a better future for Canada. Within Imperialism‚ French-speaking Canadians who preferred Canada to be self-governing and bi-lingual nation within the British Empire favoured a Nationalist ideology
