Question

I need help with questions a and b below.

An unknown compound has been determined to be one of three isomers a, b, or c as shown above. Spectroscopic measurements reveal the presence of 5 peaks in the 13^C-NMR and 4 peaks in the 1^H-NMR spectra. What is the identity of the unknown compound? An unknown compound has been determined to be one of three isomers a, b, or c as shown above. Spectroscopic measurements reveal the presence of 6 peaks in the 13^C-NMR and 6 peaks in the 1^H-NMR spectra. What is the identity ofthe unknown compound?

Explanation / Answer

Part A : The compound shows 5 peaks in 13C and 4 peaks in 1H NMR.

This data matches with "a"

b on the other hand would have only 3 peaks in 1H and 4 peaks in 13C NMR

Part b : The compound showed 6 peaks each in 1H and 13C NMR spectrum.

This data matches with compound "a"

b on the other hand would have only 5 peaks in 1H and 5 peaks in 13C spectrum. c on the other hand would show 3 peaks in 1H NMR and 4 peaks 4 peaks in 13C NMR.
