Answer to Question #168687 in General Chemistry for jas

Question

Compound given: 2,4-dihydroxybenzoic acid 

 

Requirements

1.     Draw its molecular structure 

2.     Draw its predicted ¹H NMR spectrum in as much detail as possible with respect to approximate chemical shift, integration, and spin-spin coupling pattern. Each peak should be assigned to the respective proton(s) in the molecular structure.

3.     Draw its predicted ¹³C NMR and DEPT135 spectra in as much detail as possible with respect to approximate chemical shift. Each peak should be assigned to the respective carbon(s) in the molecular structure. 

Answer 1

a)

b)

c)

DEPT135 looks the same with ¹³C.
