- what structure show the transition state for the rate determining step in the sn1 reaction with this picture?arrow_forwardRank these in order of increasing reactivity in an SN1 reactionarrow_forwardUnder second-order conditions (strong base/nucleophile), SN2 and E2 reactions may occur simultaneously and compete with each other. Show what products might be expected from the reaction of 2-bromo-3-methyl butane (a moderately hindered 2∘ alkyl halide) with sodium ethoxide. Do not worry about stereochemistry in the SN2 product for this problem. Don't forget about stereochemistry.arrow_forward
- Why are NH3 and CH3NH2 no longer nucleophiles when they are protonated?arrow_forwardFor SN1 Explain the order in which 2o (secondary) alkyl halides reacted (fastest to slowest) and explain why. 2o (secondary) compounds listed are: (see picture) 2-chlorobutane 2-bromobutane bromobenzene bromocyclopentane bromocyclohexane Base your explanations on the following considerations: the nature of leaving group, the effect of structure, steric hindrance and any other feature. Be sure to explain which alkyl halides did not react and whyarrow_forwardUnder second-order conditions (strong base/nucleophile), SN2 and E2 reactions may occur simultaneously and compete witheach other. Show what products might be expected from the reaction of 2-bromo-3-methylbutane (a moderately hindered 2°alkyl halide) with sodium ethoxide.arrow_forward
- What is the final product of the following reaction sequence? Give structural details of all significant intermediates.arrow_forwardshow the missing reagents and intermediates in the reaction sequence belowarrow_forwardIn the chemical reaction between 2-chloro-2-methyl-propane and ethanolic silver nitrate solution, a precipitate is definitely formed. Using the skeletal structures of the molecules, write out the skeletal structure of each reaction (don't include the mechanism). Identify what the nucleophile is in each type of reaction, especially within this SN1 reaction. Explain the reactivity of each electrophile/substrate in terms of whether they are tertiary, secondary, primary, etc. for each reaction. Include the overall chemical reaction.arrow_forward
- Once treated with HBr, which alkene is the most likely to undergo a carbocation rearrangement after the electrophilic addition step?arrow_forwardIn the following reaction Series, write down the appropriate reagents that can be used where there are question marksarrow_forwardSelect reagents from the table to carry out this transformation in 5 steps.arrow_forward
