- Please help with the following ochem mechanisms.... 1. Provide the stepwise mechanisms for the following reactions (see attached picture)Why does the final product has the opposite configuration compared to the reactant? Shouldn’t it form OMs first, then OMs gets substituted by Cl- via Sn2 (the 1st inversion of configuration) then the Cl- gets substituted by OCH3- (the 2nd inversion of configuration? To my understanding 2 inversions = same configurationChemistry please provide the flow of electrons aswell!! thank you! using the starting material (on the left) to determine the sythetic route which will be the most reaosnable and effective to theres none, you have to start witth the begin products to get to finish needed by using the minmium reagents and reactions needed to get to the final product
- What is (are) the elimination product(s) obtained from the following reaction? A)only I B)I and II C) I,II, and ,III D) II, III, and IVCan someone explain the answers to 28, 29, and 30? The answers are B, A, A. I understand lindar catalyst makes cis alkenes and Na/NH3 makes trans alkenes but I dont understand how the second step of Br2, OsO4 influences the stereochemistry between the 2 . Will rate quickly if helpful.
