Nucleophilic Substitution Reactions Lab (SN1 and SN2 reaction mechanisms) Below are my lab results for SN1 and SN2 reactions. This first column of the chart gives the ten starting material halides used in this experiment. The second column gives the reaction time for SN1 mechanisms with silver nitratate in ethanol solution. The third column gives the reaction time for SN2 mechanisms with sodium iodide. In theory, primary alkyl halides are expected to react faster in SN2 mechanisms, and tertiary alkyl...

answer all 1. In each of the following, indicate which S2 reaction will occur faster. Explain your reasoning. a. 1-bromo-2,2-dimethylpropane or 1-bromo-3-methylbutane with Nal in DMSO. b. 1-iodopentane with NaN, in ethanol or NaSCH, in ethanol, c. Reaction of isobutyl iodide with NaBr in acetone or in ethanol. 2. In each of the following, indicate which S, 1 reaction will occur faster. Explain your reasoning. a. Reaction of I-chloro-1-methylcyclohexane or 1-chloro-2-methylcyclohexane in aqueous ethanol. b. Reaction of 2-chloropentane or 3-bromohexane...
1. In both the sodium iodide test and the silver nitrate test, why does 2-bromobutane react faster than 2-chlorobutane? Bromine is a better leaving group since it is a weaker base than chlorine is. 2. a. Why does benzyl chloride react under both SN1 and SN2 conditions? Benzyl chloride is a primary alkyl halide, hence reactive under SN2 conditions. The primary carbocation formed due to the departure of Cl- is stabilized by the pi electrons in the benzene ring. b. Why is...
For each of the given pairs indicate which substance (A or B) will react faster in an SN2 reaction by selecting the correct compound from the dropdown menu. Then select the chemical principle why that substance has a faster SN2 reaction. Comparing Pair 1: Compound [A,B,Both Equal] has a faster SN2 reaction due to ["a better leaving group", "a worse leaving group", "more branches at the reacting carbon", "fewer branches at the reacting carbon", "more steric hindrance near the leaving...
