How many unique peaks would you expect to see in a 13C-NMR spectrum of molecule A, given that each unique chemical environment should give rise to a unique peak?
carbon with the similar chemical environment will give a single peak. carbon with different chemical environment will give different peak. therefore molecule will symmetry will have less number of carbon peak. and molecule with unsymmetrical environment will have more number of carbon peak.

Please help 3 How many peaks would you see in the 13C nmr spectrum of methyl benzoate? How many peaks would you see in the 13C nmr spectrum of methyl nitrobenzoate? NOTE: DO NOT LOOK UP THE SPECTRA BUT TRY TO DESCRIBE THE SPECTRA YOURSELF.
The 13C-NMR spectrum of an unknown organic molecule is measured. The spectrum is found to have 1 distinct peak(s) total. Assuming that each peak corresponds to a different chemical environment in the molecule, which of the following organic molecules gave rise to this spectrum? 1- ethene / 1-butyne / 3- diethylamine/ 4- butyl butanoate
1) (2 points) How many peaks would you expect to see in the: a) 1H NMR spectrum of lactic acid? (i.e. how many “types” of Hs are there?) b) 13C NMR? (i.e. how many “types” of Cs are there?)
Given the Cosey, HSQC and HMBC experiments assign the 1H NMR spectrum and 13C NMR spectrum signals of the compound. 1H peaks are labelled using lowercase letters and 13C peaks using uppercase. Be aware that the letters of the same peak does not necessarily refer to the position in the molecule. For example, peak a in the 1H and peak A in the 13C NMR are not necessarily assigned to the same number atom. The assignment of protons 4 and...
