Explanation / Answer

Interpretation of NMR

1H NMR

3.95 ppm (doublet) could be due to CH3's next to CH

7.40 ppm (singlet) could be due to CH proton

13C NMR

56 ppm and 61 ppm are for aliphatic sp3 carbons attached to electronegative element like oxygen

108 ppm is for aromatic carbon

142 ppm, 153 ppm are for aromatic carbons

172 ppm is for C=O carbon
