In this experiment we will study the rates of different alkyl halides in different reactions. There...
1. Compare the reactivity of primary alkyl halides in part 1 (SN2) of this experiment to the reactivity of primary alkyl halides today. What conclusions, if any, can you make about the reactivity of these molecules under these different conditions? Use specific data to make your point. 2. Compare the reactivity of secondary alkyl halides in part 1 (SN2) of this experiment to the reactivity of secondary alkyl halides today. What conclusions, if any, can you make about the reactivity...
1. These questions consider carbocation formation in SN1 reactions. a. Which should be more reactive in an Sn1 reaction, a primary alkyl halide or a secondary alkyl halide? b. Which reactions that you performed today compare ONLY the reactivity of primary and secondary alkyl halides and not any other effect? c. What were the reaction times for these reactions? d. Do the results of these reactions match what you would expect theoretically? e. In one or two sentences, summarize the...
Experiment 14 SN2: Synthesis of 1-Bromobutane Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as SNI (substitution, nucleophilie, unimolecular) and S2 (substitution, nucleophilie, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the S2, route and secondary alcohols can follow either path. Sth CyHe 81 CH?

16. Which of the following is correct regarding Sy2 reactions of alkyl halides? A. Secondary halides react faster than primary halides. B. Rate of reaction depends on the concentrations of the alkyl halide only. C. Favored in polar aprotic solvents D. Results in a racemic mixture
Experiment F. Nucleophilic Substitution Reactions. Pre -Lab Report 2. SPECIAL INSTRUCTIONS: a. Work in groups of 2-3 students. Each group will complete and turn in one report for grade. You will not complete the lab report in your lab notebook using the usual format. Instead, the entire report is provided in the procedures section of these lab materials. You will complete the report by providing the missing information. Report is due at the end of the lab period. b. While...
