Compound X -> C9H15NO2 (molecular mass 169g/m) undergoes hydrolysis to produce Y (72g/mol) and Z (115gr/mol)
I'm given H-NMR and IR of X and IR of Y, in H-NMR OF X the number of hydrogens from right to left is (6->3->2->4)
Z has peaks in 1715/3290/3350 in IR.
if we look at H-NMR of X, there are 4 hydrogens in the range of 5-7, these arent aromatic but vinylic and maybe the last one of them is amide H? it's so hard to tell but this is my try, am i right?
