- Draw the complete mechanism of each pair of reactants including any favorable rearrangements and all important resonance structures of all intermediates. a. Which reaction has a lower PE carbocation intermediate? b. Draw an energy diagram showing the reaction profiles of both reactions in the previous question. Use a dotted line for the first pair of reactants and a solid line for the second pair of reactants. (Assume the energy of the starting materials and products are the same for both pairs and the reactions are neither uphill nor downhill on net. c. Mark points on the energy diagram corresponding to each carbocation in your mechanisms.arrow_forwardDraw all the steps of this mechanism with arrows.arrow_forwardA pair of diastereomers is each individually mixed with a strong base, and for both an E2 reaction occurs.Provide the missing curved arrow notation, and draw the correct geometric isomer that is formed for both of the E2 mechanisms. 2nd box: Draw the major organic product with the correct geometry.arrow_forward
- #6) draw a synthesis reaction for the following mechanism. Use imagearrow_forwardDraw a detailed mechanism using curved arrow notation that leads to the formation of the major product for the pinacol rearrangement shown below. “H+” may be used for 3M HClO4 in your mechanism.arrow_forwardDraw both resonance structures of the most stable carbonation intermediate in the reaction shown belowarrow_forward
- Draw the final major product(s) for each multistep reaction.arrow_forwardOchem help... What is the major product of the following reaction sequence? Provide the stepwise mechanism for each step (1, 2a, and 2b). (see attached image)arrow_forwardSometimes carbocation rearrangements can change the size of a ring. Draw a stepwise, detailed mechanism for the following reaction.arrow_forward
- Identify the lettered compounds in the following reaction scheme.arrow_forwardFor the following transformation can you identify if it involves reduction, oxidation or neither? Can you explain how you know?arrow_forwardHow many transition state/s is/are present in the reaction based from the energy diagram as shown below?arrow_forward
