Evaluate and investigate the
following IR 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
C from this multi-step synthesis where Product
B 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
