Chapter 10 Worksheet 1. Name the subatomic particle below, including any stereochemistry. travel by the product(s) of an SN2 response with this and I- as the nucleophile. Now draw the product(s) of an SN1 reaction with the buffer molecule and I- as the nucleophile. Finally, draw complete mechanisms for these two reactions. [pic] (S) 2-Bromohexane SN2 mechanism [pic] SN1 Mechanism Step 1 [pic]Step 2 [pic] 2. line of dally #28, p393 a. OH- is a break away nucleophile, so it is faster b. I- is a best exit grp, so it is faster c. NH3 is a better base, and t presentfore a better nucleophile than water, so it is faster d. DMSO is a polar, aprotic solvent, allowing a naked nucleophile to react faster e. here is a case where either answer would be patch up, providing it is correctly confirm. unrivalled could say that the polar, aprotic solvent ethoxyethane would not entomb the nucleophile, make the reaction go faster (as per DMSO, above). But because ammonia isnt a great nucleophile, there is another musing (explained on p391). If neither of the reactants is charged (methyl bromide and ammonia ar both uncharged), the more than polar solvent is better adequate to brace your SN2 transition state. This is one of those cases where there are two things to consider, and all(prenominal) will give a different answer.

At our level, it is not dire that we know which one of these things has more lading below which set of conditions, so either answer would be correct as long as you have justified your answer. 3. For apiece of the following conditions, indicate whether the substitution reaction is mo re credibly to be SN1 or SN2?. a. nucleo! phile is OH-SN2- good nucleophile b. nucleophile is H2OSN1- despicable nucleophile c. solvent is nonpolarSN2- no carbocation possible d. alkyl radical halide (reactant) is CH3BrSN2-Leaving group on methyl C e. alkyl halide is primarySN2-Leaving group on 1° C f. alkyl halide is tertiarySN1-Leaving group on 3° C g. leaving...If you command to chance a full essay, order it on our website: OrderEssay.net
