Explanation / Answer

Charaterization of the organic compound

For the given aromatic acid amide compound

1H NMR

2.15 ppm : g (CH3 protons, 3H)

7.15 ppm : c (aromatic CH proton, 1H)

7.58 ppm : d (aromatic CH proton, 1H)

7.99 ppm : e (aromatic CH proton, 1H)

8.5 ppm : b (aromatic CH proton, 1H)

11.1 ppm : a (carboxylic acid proton, 1H)

---

13C NMR : carbon number

24.84 ppm : 9

116.77 ppm : 5

120.11 ppm : 6

122.44 ppm : 4

130.98 ppm : 7

133.75 ppm : 3

140.90 ppm : 2

168.29 ppm : 8

169.33 ppm : 1

----

IR

3100-2500 cm-1 : O-H stretch of -COOH group

2909 cm-1 : sp3 C-H stretch

1646 cm-1 : C=O stretch

1604 cm1 and 1450 cm-1 : C=O and C-O stretch

1578 cm-1 : C=C stretch

The others can be determined by experimental results.
