Question

I need help with filling out the CNMR information please

1)DEPT Phase for each peak (positive, negative or null)

2)Group based on DEPT (possible choices are CH3, CH2, CH or C)

3)label the peaks to the corresponding carbon on the structure
2-chlorobenzaldehyde

Thank you!

Explanation / Answer

13C NMR

Compound 2-chlorobenzaldehyde

First spectrum,

127.3 ppm for CH of aromatic ring

129.4 ppm for CH of aromatic ring

130.68 ppm for CH of aromatic ring

135.22 ppm for CH of aromatic ring

132.5 ppm for C of aromatic ring

138 ppm for C of aromatic ring

189 ppm for carbon of C=O group

77 ppm for CDCl3

Quaternary carbons at 132.5 and 138 ppm disappear in the second spectrum shown above
