Chapter 10 Worksheet 1. Name the subatomic particle below, including any stereochemistry. leave off 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 first molecule and I- as the nucleophile. Finally, draw complete mechanisms for these some(prenominal) reactions. [pic] (S) 2-Bromohexane SN2 mechanics [pic] SN1 Mechanism Step 1 [pic]Step 2 [pic] 2. line of thrash #28, p393 a. OH- is a break away nucleophile, so it is faster b. I- is a go 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 set, providing it is correctly confirm. whiz could say that the polar, aprotic solvent ethoxyethane would not entomb the nucleophile, reservation the reaction go faster (a s 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 perk up your SN2 transition state. This is one of those cases where there are two things to consider, and severally will give a different answer.

At our level, it is not dire that we know which one of these things has more lading low which set of conditions, so either answer would be correct as long as you have justified your answer. 3. For distribut ively of the following conditions, indicate ! whether the substitution reaction is more in all likelihood to be SN1 or SN2?. a. nucleophile is OH-SN2- good nucleophile b. nucleophile is H2OSN1- despicable nucleophile c. solvent is nonpolarSN2- no carbocation possible d. alkyl group 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 loaf a full essay, order it on our website: OrderCustomPaper.com
