Compound C
1H NMR
The peak 5.0 ppm belongs to CH which is attached to oxygen. The peak 1.2 ppm shows doublet which is attached to CH. Both peaks responsible for isopropyl group.
The peak at ~2.0 ppm belongs to methyl group. Because the intergration is three. It may be attached to carbonyl oxygen.
Using the information we can deduce the structure.
Compound D
1H NMR
1H NMR shows two doublets from 6-8 ppm that belongs to aromatic proton and the pattern confirms that the ring is substituted at 1,4 position.
The peak 12.5 ppm is responsible for COOH group.
The peak at ~2.0 ppm belongs to methyl group. Because the intergration is three. It may be attached to aromatic ring.
Using the information we can deduce
the structure.
