Using the data provided below. Fill out the tables regarding the
FTIR and NMR Spectra for 2-methyl-2-ethoxypropane.
FTIR and NMR Spectra After completing a reaction and working up the products, it is still necessary to confirm that the correct product was formed. The most common tools used for this analysis are Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. In the virtual laboratory, 'H and ''C NMR spectra are available. Details on interpreting FTIR and NMR spectra are...
