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° ). 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

Comparison of Three Isomers of Butanol SCH 4UI Abstract The Hydroxyl group on alcohols relates to their reactivity. This concept was explored by answering the question “Does each alcohol undergo halogenation and controlled oxidation?” . Using three isomers of butanol; the primary 1-butanol‚ the secondary 2-butanol and the tertiary 2-methyl-2-propanol‚ also referred to as T-butanol‚ two experiments were performed to test the capabilities of the alcohols. When mixed with hydrochloric acid in

LAB: Comparison of Reactions for Three Isomers of Butanol /23 TI /21 C /6 A Name: /50 MARKS Background: The reactivity of alcohols can be accounted for by their molecular structure – particularly by the attachment of their hydroxyl functional group. The isomers of butanol are used as examples of 1°‚2° and 3° alcohols to examine this relationship. Each of the three isomers of butanol will be mixed with concentrated hydrochloric acid. The presence of an alkyl halide product is

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

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 and SN2 reactions‚ so we of course used the hydrobromic

Experiment 28: The reaction of Butanols with Hydrobromic Acid Pre-lab Objective: The objective of this experiment is to synthesize 1-bromobutane and 2-bromobutane with different catalyst:substrate ratios to determine which ratio is the most economically favorable. Discussion: In this experiment‚ 1-butanol or 2-butanol will be converted to the corresponding alkyl bromide with HBR‚ while using sulfuric acid as a catalyst. The sulfuric acid will accelerate the chemical reaction with being consumed
