The molecular formula is CuHuNO2. Place your answers in the boxes on the following page. (a) Provide a structural formula which is consistent with all of the given information; give the degrees of unsaturation (DoU). (b) For the 'H NMR spectrum, make a table in which you assign, as best as possible, the chemical shift of each H in the structural formula that you gave in part a. Also give in your table the number of Hs (integration value), and...
