Discussion and Conclusion: Preparation of 1-Bromobutane The purpose of this experiment was to demonstrate the conversion of a primary alcohol‚ 1-butanol‚ to a primary bromoalkane‚ 1-bromobutane‚ a SN2 reaction. The conversion of 1-butanol to 1-bromobutane relies on sulfuric acid which plays two important roles. First‚ it protonates the alcohol of 1-butanol to form an oxonium ion which is a good leaving group. Secondly‚ it produces the hydrobromic acid‚ the nucleophile‚ which attacks 1-butanol

Restriction Endonuclease Digestion of DNA from E. coli cells and Analysis by Agarose Gel Electrophoresis Introduction The main goals of this experiment are testing an alternative procedure called “boiling lysis”‚ evaluating the quality of the purified plasmid for restriction digests‚ and identifying the mislabeled plasmid. The plasmid DNA from a carrier E. coli strain was purified by the boiling lysis. In the boiling lysis method‚ the bacterial cells were given momentary heat treatment

represented by 5Br—(aq) + BrO3—(aq) + 6H+(aq) → 3Br2(aq) + 3H2O(l) The progress of the reaction may be followed by adding a fixed amount of phenol together with some methyl red indicator. The bromine produced during the reaction reacts very rapidly with phenol. Once all the phenol is consumed‚ any further bromine bleaches the indicator immediately. So‚ the time for the reaction to proceed to a given point may be determined. Requirements: Apparatus: Beaker Burettes Boiling tubes Stop-watch

Objective: The purpose of this lab was to use transfer hydrogenation to saturate glycerol trioleate (the main fat in olive oil) to produce glycerol tristearate. Reaction Equations: Theoretical Yield: There was no Theoretical yield in this experiment Procedure: Fill a 50 mL beaker with 30 mL of water and place it on the hot plate. Add 14 drops of olive oil to a 10 mL round bottom flask and then add 1 mL of cyclohexene. Add .05 grams of 10% palladium-on-carbon to the round bottom flask

Cyclohexene From Cyclohexanol 5/29/14 Abstract: A 42.89% yield cyclohexene was successfully synthesized from 10.0 mL cyclohexanol by unimolecular elimination (E1) through the dehydration of cyclohexanol and confirmed via a bromine test and the IR spectra. Introduction: Alkenes are hydrocarbons that have carbon–carbon double bonds and are one of the many functional groups in organic molecules. Alkenes are sp2 hybridized and are unsaturated because two of their hydrogen’s

reaction. In order to separate the cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used. The formation of the product was verified by performing a Bromine test as well as an analysis using IR Spectroscopy. A percent yield of 8.33% was obtained. Introduction: In an elimination reaction‚ two substituents are removed from a molecule in either a one or two-step mechanism. There is a removal of a leaving
