The color changed to a light white color. | 2-chlorobutane | lt;30 sec | cloudy | The mixture turned cloudy within 30 seconds. | 2-bromobutane | lt;30 sec | cloudy | The mixture turned cloudy within 30 seconds | 2-chloro2-metylpropane | immediately | cloudy | The mixture was reactive on entering the test tube. The color changed from clear to cloudy. | 2-bromo-2-methylpropane | immediately | cloudy | The mixture was reactive on entering the test tube. The color changed from clea r to cloudy. | Crotyl chloride | No reaction | | | Bromobenzene | lt;2min | Slightly cloudy | With in 2 minutes it was determined that the mixture was reactive. The color changed from clear to slightly cloudy | Benzyl chloride | immediately | cloudy | The mixture was reactive on entering the test tube. The color changed from clear to cloudy. | 1-chloroadamantene | About 10 min | cloudy | After about 10 minutes the mixture turned cloudy and was found to be moderately reactive. | Conclusion: I this experiment, it was concluded that the time in which it took the substrates to react by indication of a cloudy color in the the Sn1 reactions and a yellow color in the Sn2 reactions, was a direct result of reactivity of the alkyl halides in thisShow MoreRelatedSynthesis of 1- Bromobutane an Sn2 Reaction1160 Words   |  5 PagesExperiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However, they are a poor leaving group the OH group is a problem in nucleophilic substitution, this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction, to see howRead MoreNucleophilic Substitution: Synthesis of N-Butyl Bromide and T-Pentyl Chloride1608 Words   |  7 PagesNucleophilic Substitution | Synthesis of n-Butyl Bromide and t-Pentyl Chloride | | Jessica | [Pick the date] | Abstract The synthesis of the alkyl halide n-Butyl Bromide from alcohol is the foundation for the experiment. During the isolation of the n-butyl bromide, the crude product is washed with sulfuric acid, water, and sodium bicarbonate to remove any remaining acid or n-butyl alcohol. The primary alkyl halide halide n-butyl bromide is prepared by allowing n-butyl alcohol to react withRead MoreOrganic Chemistry Lab Report4021 Words   |  17 Pagesmethods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings. 1. Your work is unique, meaning that you might be the only person performing certain experiments. 2. Research is an ongoing process. The projects assigned to you will likely continue after you leave. People assigned to those projects will need to access your records for reference, or to attempt to
