This is the Wittig reaction. Below I have the reaction performed. So first we have the IR of starting material and then the product, all the peaks for all IR. Please identify the peaks in all the IR. Please also explain the difference observed thank you!. For this reaction an NMR is also performed, have to label the H NMR based on the product formed also based on the values given have to determine if the product was cis -9-2(...
Based on the Wittig Reaction exp. below, please answer a) and b). In b) you can disregard the part about the IR, just please interpret and assign protons, shift values, which protons are for which groups, etc on the HNMR. The % yield was 34%, and MP was lower than expected (to assist with answering part a). This should be all the information you need to answer the question. HNMR Discuss the percentage yield of the reaction. Explain and provide...
What is the objective of this experiment? The reaction solvent for this experiment is xylene. What property of this solvent makes it a better choice than toluene or benzene? Draw the orbitals involved in the 4+2 electrocyclization for this reaction. Draw the structures of the reactants as best you can. It may be appropriate to abbreviate the structure of anthracene. IR is not provided for this reaction product. Why is IR not useful for monitoring the reaction or characterizing the...
