    • 5 Pages

    Reaction Experiment #13: Synthesis of 1-Bromobutane an SN2 Reaction Introduction: In order to synthesize 1-Bromobutane an alkyl halide must be present to undergo a nucleophilic substitution reaction of an alcohol. Since 1-butanol is a primary substrate it will undergo an SN2 reaction with sodium bromide in order to convert the alcohol group to water which is a better leaving group and will in the end produce 1-bromobutane. Experimentally the lab students will see the reaction

    to dissolve the salts. We put 17mL into a separatory funnel for use in the second reaction‚ and placed the rest into a reflux apparatus for our first reaction. We performed the first reaction of the competitive nucleophiles with 1-Butanol. We added 2.5mL of 1-butanol to the solvent-nucleophile medium in the reflux apparatus with a boiling stone and heated the mixture under reflux for 75 minutes. After reflux was completed‚ we allowed it to cool in an ice bath‚ and transferred the solution to a

    the sulfuric acid. We used heat to help the solutes dissolve. When they had dissolved‚ we allowed the flask to cool and then poured 17 mL of the solution into a separatory funnel and the rest of the solution into the reflux apparatus. 2.5 mL of 1-butanol was added to the reflux apparatus along with a boiling stone. We then started the circulation of water and brought the mixture to a gentle boil for 75 minutes. After that time we allowed it to cool in an ice bath. We then transferred the solution

    Technetium-99 Technetium-99 (Tc-99m) is used tens of millions of times annually. Approximately 85% of diagnostic procedures in nuclear medicine use this radioisotope. Making it the most common radioisotope used in diagnosis. Technetium-99 is used as a radioactive tracer and is detected in the body by gamma cameras. Technetium-99 is produced by bombarding Molybdenum with neutrons‚ producing Molybdenum-99. This then goes through a Beta decay with a half-life of 66 hours and produces Technetium. Technetium-99

    1-bromobutane. Designate how each minor-product is removed from the major product and which layer holds the product in each experimental step performed. [pic] Introduction This experiment utilizes SN2 chemistry to convert 1-butanol (n-butanol) to 1-bromobutane (n-bromobutane). The nucleophile for the reaction is Br- ions. The nucleophile in this lab is generated from an aqueous solution of sodium bromide. The sulfuric acid acts as a catalyst in converting
