An excellent way to identify the presence of an aldehyde group is by 1H NMR. The chemical shift of the aldehydic proton occurs in the 9-10-ppm region, where few other proton signals occur. Why is this chemical shift so far downfield?© BrainMass Inc. brainmass.com October 10, 2019, 1:06 am ad1c9bdddf
Hydrogen nuclei are very sensitive to the hybridisation of the atom to which the proton is attached and to electronic effects ...
The expert examines the chemical shift that occurs with the presence of Aldehyde group. Why the chemical shift is so far downfield is determined.
