Answer the following questions about radical halogenation QUESTION 1 Performing allylic bromination of an asymmetric alkene produces two regiochemical outcomes due to resonance, and two conformations (R) and (S) for each chirality center produced. This is further complicated if you make the mistake of using Br2 as your source of bromine radicals, as the addition reaction producing alkyl dibromides competes with the allylic bromination. Br2, hv ??? Categorize each of the compounds shown below as an [A] allylic bromination product,...
Look up and draw the mechanism for the addition of Br2 to double bonds. Reference the source from which you acquired the mechanism. Give the IUPAC name of the major product in the above-mentioned reaction. Draw the major product of obtained in the addition of Br2 to stilbene. Is this isomer chiral? What would be the optical rotation if this sample was placed in a polarimeter? Would a student obtain the same product if you started with cis-stilbene instead of...
one possible answer is a wittig rxn. please explain how? 4) Consider the following retrosynthetic analysis: this way more than 1 Product Br This is one potential way to form the target alkene on the left: elimination from the corresponding alkyl halide. What's another unique pathway (can't involve an elimination) that would allow you to form this alkene? Describe this alternative. Would there be an advantage to this alternative pathway? What would that be? (20 Pts)
What is Wrong? Select the keyword or phrase that will best complete each sentence. Key terms: A radical is a reactive intermediate with a single unpaired electron, formed by homoloysis of a covalent bond. paired unpaired Allylic radicals are stabilized by resonance, making them more stable than tertiary radicals increases inductive effects A compound that contains an especially weak bond that serves as a source of radicals is called a radical initiator ess homoloysis decreases more J Treatment of cyclohexene...
How do I answer questions in number 6 please, Thanks 6) (12 points) Draw mechanisms for the following transformations +HC HO Br2 + HBr H3C H3 hv H3C rパ HO Br H2O + HBr c) (Hint for Se: Doubling the concentration of water has no effect on the rate.) 7.) (4 points) For the reaction in question 6b,t below is seen product, and what product ratio of question 6b is in fact the major prod stabilities of intermediates involved in...
Can you help me identify reagent (i), Compound 8 and Compound 12 in the reaction scheme? You have laboratory data on all the compounds in the synthesis, however the amount of data available to you varies. Some have the entirety of the spectral data, others have as little as the elemental analysis. Use the laboratory data to help you discover which reaction has been performed. The lab data for Compound 8 and 12 is as follows: You can use any...
1st picture is the questions and the next two pictures are the experiment the questions are based off of Prelab Questions 1) Based on the Material Safety Data Sheets (MSDS) for the compounds, which of the compounds in this experiment is the most hazardous, and why? 2) Fill in the reagent table below. Make sure you correctly calculate the molar amounts of your materials. Name Formula Mol.-eq. Mw mmol Density/Conc. Amount 10 400 mg Meso-Stilbene Dibromide Potassium Hydroxide 5.75 Triethylene...
Postlab Questions Answer the following questions on a separate sheet or in your lab notebook. Make sure that the copy page is readable! D) Calculate the percentage yield for both reactions. Show all calculations. 2) What is the color of the reaction at the beginning of reaction?
