Please help me with the organic chemistry problem below: Consider the reaction below: (Check the attached image) (it is between Furan and maleic anhydride, a DIels-Alder reaction) a) Will this reaction for an endo product (with a melting point of 80-81 degrees) or the exo product (with a melitng point of 114 degrees)? b) Carefully explain why the product must have been formed the way it did (exo or endo). c) Provide a mechanism for this reaction.
5. Write a detailed chemical mechanism for the following reaction. [10 pts] NBS hv ? For full credit, • Explicitly label initiation, propagation, and termination steps. • Use 'curly arrows' to denote electron flow. Show all resonance forms of the reaction intermediate(s). N-Br NBS (N-bromosuccinimde) • Show reaction at any resonance forms of the reaction intermediate(s) that lead to different products. including constitutional and stereochemical isomers (if any). Show two different termination steps. Showing more steps will not earn points; wrong steps will lose points
3. An alkene can be converted into an ether in the three mechanistic steps shown below. Complete this mechanism by: Draw curved arrows to indicate the flow of electrons for each step. Lone pairs are omitted for clarity but be sure to include lone pairs on atoms that are involved in bond formation/breaking. Draw the reaction intermediates in the appropriate boxes. Include all nonzero formal charges. Classify each step of the mechanism using the boxes below each arrow as one of the following: acid- base proton transfer (AB), nucleophilic attack (NA), elimination (E), or rearrangement (R). + H-OMe H-OO + MeOH + MeOH + H-OMe H-OO 48
Give a detailed reaction mechanism for the reaction expected to occur when 2-bromo-2- methylpentane is heated with sodium methoxide. • Draw clear structural formulas of all relevant species and use curved arrows to represent electron flow. Indicate which step is likely to be rate determining.
6. Draw a plausible multi-step mechanism for the following transformation. Remember to use the correct arrow conventions for indicating electron flow and to keep track of relevant lone pairs and formal charges. Draw all products of each step, organic and inorganic. H S. Br Na : H S
