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...
would anyone be able to help me solve these questions? im unsure what its even asking 4When the starting material shown below is treated with a variety of bases in DMSO (solvent) at 50 C, the percentage of 1-butene formed among total butenes is found to be dependent on the choice of base, as seen in the chart below (J, Am. Chem. Soc. 1973, 95, 3405-3407). base +other products DMSO 2-jodobutane 1-butene 50°C Н,с Structure of Base FyC ethoxide 2,2,2-trifluoroethoxide...
Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
Separating a Mixture, Recrystallization, pre-lab assignment could you also explain why you chose that substance for the empty spaces and question marks EXPERIMENT 4 Pre-Lab Assignment Separating a Mixture, Recrystalliration Name Date 1. Complete the following flowchart which shows how to separate a mixture of sand, sodium chloride and acetanilide. Notice that after a separation process (a down arrow) the filtered solids are shown on the left and the filtrate (the liquid) is shown on the right. The terminal step...
