Draw both resonance structures of the enolate formed when each of the following ketones is treated with a strong base. Show mechanisms.
1) Which base yields the most SN2 when treated with the same starting material? (draw this structure with stereochemistry) 2)Which base would have the least yield of SN2? 3) What conclusions are made about the amount of SN2 product formed as a function of base strength? 4) Discuss stereospecificity of an SN2 reaction and draw the SN2 transition state intermediate formed when benzoate is treated with starting material. 4. When the starting material shown below is treated with a variety...
Draw both resonance structures or draw the major organic product(s) as outlined in the instructions. Draw both resonance structures of the anion formed by the reaction of the most acidic C-H bond of the compound below with base. H3C OCH Include all valence lone pairs in your answer. For structures having different hydrogens of comparable acidity, assume that the reaction occurs at the less-substituted carbon. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom...
Two major resonance structures are possible for the following anion. One resonance form is given below, but it is incomplete. Complete the given structure by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges. Omit curved arrows. Which structure contributes most to the hybrid? Both contribute equally. The structure with the negative charge on nitrogen. The structure with the negative charge on carbon.
