View notes - lab #1 from chem 210 at northwestern university synthesis of t-pentyl chloride abstract the synthesis of t-pentyl chloride from t-pentyl alcohol was attempted through an sn1 reaction. Kirby williams section: 01 instructor: curtis experiment 23a, c: synthesis of alkyl halides completed: 29 october 2012 purpose: the purpose of this experiment is to perform a synthesis of two alkyl halides, n-butyl bromide, and t-pentyl chloride from alcohols the further practice of extraction and distillation will be executed. Experiment 23a – synthesis of n-butyl bromide – name _____ oh nabr, h 2 so 4 br 1 data table: fill in the appropriate spaces in the data table below under the amount column, use g for solids, ml for liquids the abbreviation na stands for not applicable.
A sn1 reaction: synthesis of tert-butyl chloride supplementary material experiment notes: this lab experiment proposes the synthesis of an alkyl halide by reacting the optimizing the reaction conditions for the synthesis of tert-pentyl chloride supplementary material. Experiment 23: synthesis of n-butyl bromide and t-pentyl chloride - microscale - pavia 99 questions n-butyl bromide t-pentyl chloride dry the crude tert-pentyl chloride over 10 g of anhydrous calcium chloride until it.
In order to synthesis t-butyl chloride from t-butyl alcohol, hydrogen chloride is used to react with it during the reaction take places, the t-butyl alcohol undergoes first order nucleophilic substitution, s n 1 mechanism since t-butyl alcohol is a tertiary alkyl group. Table 1: aqueous washings of n-butyl bromide product wash with: 1st rdwater conc sulfuric acid 2nd water 5% naoh (aq) 3 water n-butyl bromide layer: top top bottom bottom bottom (this water wash layer may be more dense than n-butyl bromide because of salts dissolved in the water. Ch 2020/2270/2290 synthesis of n-butyl bromide from n-butanol (an s n 2 reaction) sodium iodide is soluble in this solvent, whereas sodium chloride and sodium bromide are not if a reaction occurs, a precipitate of sodium chloride or sodium bromide forms the mechanism involves a one-step, concerted, s n.
This lab experiment proposes the synthesis of an alkyl halide by reacting the corresponding alcohol with a hydrogen halide in an easy and inexpensive sn1 reaction 1,2 tert-butanol reacts readily with hcl and forms the corresponding tert-butyl chloride at room temperature sn1 mechanisms are unimolecular because its slow step is unimolecular. The sn2 mechanism was observed through the nucleophilic attack of bromide ions on n-butanol to form n-butyl bromide, and the sn1 mechanism on the other hand was observed with the formation of tert-butyl chloride from tert-butanol.
