From the given two graphs,
We can see that, there are fewer peaks in the NMR after 30 minutes than NMR after 3 hours. Also, amplitude of the peaks have increased as time passed. It is due to reason because when we perform NMR spectroscopy on a reaction mixture, initially, only few protons are aligned in the direction of applied field. As time passes, more protons start to align in the direction of applied magnetic field. Therefore, intensity of the NMR spectra increases with time.

For the determination of the structural formula of aromatic
compound A, the 1 H-NMR spectrum was obtained, which is given
below.
Compound A was subjected to the five (5) stage experiment,
which follows. It is stated that in Stage I the yield was 45%,
while for the remaining stages the yield was 100%.
Step I: Amount of 0.02 mol of Compound A after treatment with
concentrate NaOH under the appropriate conditions, gave the organic
products B and C.
Step II:...

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 found in your textbook. Your instructor may or may not...
