Evaluate and investigate the following IR Spectrum, 13C NMR Spectrum and 1H NMR Spectrum. Identify the most important peaks and correlate the results as much as you can from the obtained product in the multi-step synthesis of ethyl acetoacetate. This is Product E from this multi-step synthesis where Product C was identified as in the figure below and as such, identify what product can be obtained after the synthesis from the spectra provided. Use the template below in analysing the...
