H NMR spectrum
IR spectrum
Based on your measurement of the dihedral angle on the molecular models, which of the two possible products will have the smallest coupling constant between the two hydrogens indicated? Based on the splitting pattern seen in your 'H NMR spectrum, which product have you isolated? Conclusion Answer any of the questions in the above procedure and assign the peaks in the 'H NMR due to your product. Carefully explain the splitting pattern that your observe for all peaks in the 'H NMR (drawing tree diagrams will be useful here) and assign the peaks in the IR due to the product weight of product 21.1319 Melting point of product = 100-101C amount of maleic anhydride used:1.3089 dinedral angle: Endo = 35 Exo = 80 Equation Juri = 10 costo vvv a: fiddata.nmr ausrution 6.596 400 6.581 6.566 triplet triplet 3312 Abray 200 0 www.
