- The reaction shown here, which converts an epoxide into a bromohydrin, is discussed in Chapter 10. It consists of the two elementary steps shown. For each step (i and ii), (a) identify all electron-rich sites and all electron-poor sites, (i) H H-Br BrO + H3C (b) draw in the appropriate curved arrows to show the bond formation and bond breaking that occur, and (c) name the elementary step. (i) BrO Но H3C H3C Brarrow_forwardThe initial rates for the following elimination reaction were measured under different concentrations of the substrate and base (water); the data are tabulated at the right. Do the data suggest an E1 reaction or an E2 reaction? Trial Number [R-OCH3] [H,O] Rate (M/s) 1 0.010 M 0.45 M 9.50 × 10-4 H,O 0.020 M 0.45 M 1.85 × 10-3 OCH3 CH3CN, H 3 0.020 M О.22 М 1.85 × 10-3arrow_forwardDetermine whether the addition of a nucleophile to the O atom of a C=0 group is allowed or forbidden. If you determine that it is allowed, would you expect that elementary step to take place? Why or why not?arrow_forward
- Each pair of reactions, 1 and 2, will both go by the same mechanism, Sn1 or S2, say which. Explain why your choice of mechanism. Also, say which of the two in each you expect to go faster, or the same, and explain why your choice goes faster.arrow_forwardWhich mechanism(s) would be favored under the following reaction conditions?arrow_forwardHow do we know whether a reaction occurs by the E1 or E2 mechanism?arrow_forward
- If Hj is eliminated from the carbocation shown here in an electrophile elimination step, then three possible constitutional isomers can form. Draw the mechanism for the formation of all three of those products. H20 +arrow_forwardDraw the mechanism and the energy diagram for the reaction shown below. Include any resonance structures for the intermediates of the reaction. H3O+arrow_forwardWhich of the following two reactions would you predict to go faster and why?.arrow_forward
- For the given SN2 reaction, draw the organic and inorganic products of the reaction, and identify the nucleophile, substrate, and leaving group.arrow_forwardDoes the reaction likely proceed by the SN1, SN2, E1, or E2 mechanism?arrow_forwardThe free energy diagrams for an E1 reaction mechanism and for an SN1 reaction mechanism are very similar except that there are no differences; they are identical. the intermediate(s) is/are at different energies. the overall products are at different energies. the overall reactants are at a different energies. an SN1 reaction includes two intermediates, while an E1 reaction includes one intermediatearrow_forward
