- The following reaction resulted in the product shown below, but not the other product shown. Using the reaction mechanisms and chemical structures, explain why their products was obtained. The product was obtained as a racemic mixture.arrow_forwardPlease provide the mechanism and reagents for this reactionarrow_forwardPlease solve the following reaction mechanisms for various compounds (ketone, aldehyde, alcohol, carboxylic acid, amine) in the presence of diethyl ether (solvent). These reactions occured to test their solubility in ether and all were found soluble.arrow_forward
- What is the mechanism (in detail) of the following reaction?arrow_forwardA student found that heating any one of the isomers shown here resulted in scrambling of the deuterium to all three positions on the five-membered ring. Propose a mechanism to account for this observation.arrow_forwardWhat is the major product structure? Provide the detailed mechanism of this reaction pleasearrow_forward
- When phenyl-5-bromopentanone is treated with triphenylphosphine, followed by base, a compound is produced whose formula is C11H12. Its 13C NMR spectrum has nine signals, six of which appear between 120 and 140 ppm and three of which appear below 50 ppm. For this reaction, draw the complete, detailed mechanism, as well as the major organic product. 1. P(C6H5)3 Br C11H12 2. NaOCH,CH3arrow_forwardThis reaction proceeds through a series of two elimination reactions. Which elimination do you believe is rate determining in this process and why?arrow_forwardThe phenyl group, C,H5, is known to be an ortho/para-directing group. (a) With that in mind, predict the product of the reaction shown here. (b) Justify why it is an ortho/para director by drawing the ortho, meta, and para arenium ion intermediates that would be formed during the course of the reaction. Br2 FeBraarrow_forward
