- 7. Draw the complete mechanism for the following transformation. Include arrows, formal charges, lone pairs, and resonance structures where applicable. H₂CN НО H₂O H₂C NH₂arrow_forward4. Synthesis Using the carbon-containing starting material(s), propose a synthesis by drawing structures for all intermediates. The carbon atoms in the product must originate from the starting material(s) (or a carbene/carbenoid or CO₂), but you may use as many equivalents of each starting material as you would like, and any reagent/reaction you know. (note: no mechanisms are required). (a) || محمد barrow_forward5. Each of the following may participate in an elimination reaction, under the proper conditions. (a) Circle the alpha (a) carbon. (b) Circle the beta (B) carbon(s). (c) Draw the alkene product(s) that may form, with the new double bond between the a and B positions. (d) If more than one alkene product is possible, circle the most stable (Zaitsev) product. X tx + 3arrow_forward
- 4) Draw the complete electron-pushing arrow mechanism for the following reductions. Explain, using resonance contributors, the regiochemistry that results in each case. ỌMe Na, MeOH ? NH3 CHO Na, MeOH ? NH3arrow_forward2.) Show the complete mechanism and the major product formed from the reactions below. OMe CH,CH,OHarrow_forwardQuestion 5. (20 points) Consider the following reaction. + PhLi (2 eq.) then water a) Propose a structure for the final product. b) Give a complete mechanism for the transformation. c) Draw an energy diagram of the transformation and briefly comment on the relative energies of the starting material, final product, and any intermediate(s), and about the rate determining step.arrow_forward
- Use the E2 mechanism to explain why when I is mixed with sodium ethoxide (NaOEt) in ethanol, the major product is III, but when II is mixed with sodium ethoxide in ethanol, the major product is IV. H3C CH3 H3C CH3 ..CI CI CH3 I CH3 || H3C. CH3 H3C CH3 E ||| CH3 CH3 IV SANarrow_forwardWhat major product (from Figure #1) results from the following dehydration reaction (from Reaction #1)? Reaction #1 HO, H2SO4 heat Figure #1 compound A compound B compound C compound D Please click here if image does not display. In predicting the major product of boxed reaction #1, it is strongly recommended that you work out a complete mechanism on a piece of scratch paper. compound C compound A compound D compound Barrow_forward1. For the reaction in Fig. 9 draw the curved arrows and the structure of the transition state. H to Figure 9: Draw curved arrows and the structure of TS H₂O محمد OO-Harrow_forward
- 3) Draw the major organic product generated in the reaction below. CH3 HCI |arrow_forwardDraw a mechanism for this reaction. H₂C- CH3 -0- Interactive 3D display mode -CH3 H₂C CH₁₂ H₂C-O i Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be created.arrow_forwardShow the steps of the next reaction in detail. And explain why it's hard to go along with the dotted line.arrow_forward
