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

-1Determination of an Unknown Liquid (2-butanol) Through Fundamental Analysis Lee Billips Department of Chemistry‚ Shippensburg University‚ 1871 Old Main Drive. Shippensburg‚ PA‚ 17257. Abstract: The identification and characterization of unknowns are an important part of organic chemistry. It is fundamental to know experimental methods to deductively identify compounds (1) . The determination of unknown #6 (2-butanol) was identified by a series of test; first taking the boiling point (94-96

Lab Protocol #8 - Dehydration of 3‚3-dimethyl-2-butanol KEYWORDS: alkenes‚ E2‚ E1‚ carbocation stability‚ elimination A. Introduction. The dehydration of alcohols is an ELIMINATION reaction that is commonly used to form alkene molecules. The mechanism for the dehydration of alcohols consists of transforming the –OH functional group into a better leaving group by using a strong acid to protonate the alcohol. After –OH has been transformed into –OH2+‚ it becomes easier to break the σ-bond between the

Comparison of Three Isomers of Butanol Introduction An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). The purpose of this experiment is to observe and predict the reactions that take place between all three alcohols and an oxidizing agent‚ as well as to test our theories of how the

Introduction The production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest

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

of Three Isomers of Butanol Introduction: An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). If the OH is bonded to only one other carbon‚ it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons‚ it is a secondary alcohol (eg. 2-butanol); if bonded to three

use of tert-butanol was needed to perform phase changes. Tert-butanol is colorless oily with sharp odors‚ mixes with water‚ and has a freezing point of 78 degrees Farenheit (PubChem‚ 2016). This substance allows for proper testing due to its freezing point being at room temperature. Tert-butanol can easily show how the process of phase changes can happen without having to take the time to freeze a different substance. It is also necessary to note the molecular formula. Tert-butanol is C4H10O‚ which

Discussion: For this experiment our primary goal was to observe and note the reaction of butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1
