I think I have a ketone here, but am unsure of how to label each peak and fit them to a structure. I don’t think it fits the names I’ve guessed ie. 2-methyl-3-hexanone Edit: The intent of this was to perform tests to determine the name of an unknown liquid - unfortunately I was not given the empirical formula or any other information other than what I found experimentally. What I know is that based on tests I performed such as dinitrophenylhyrdazine, tollens, schiff etc. the substance is likely a ketone. However, I don\'t know how to analyze this data properly. Relative Intensi 8 8 Solution In 13 C spectram, there is peak around 220 ppm which indicates the peak of C=O group of ketone. But your mass spectra is not visible. You have guessed i.e. 2-methyl-3-hexanone , but it is not 2-methyl-3-hexanone because it has total 14 H and your 1 HNMR is showing total 10H. So, It is sure there is a ketone molecule. .

In 13
C spectram, there is peak around 220 ppm which indicates the peak of C=O group of
ketone. But your mass spectra is not visible. You have guessed i.e. 2-methyl-3-hexanone , but it
is not 2-methyl-3-hexanone because it has total 14 H and your 1
HNMR is showing total 10H.
So, It is sure there is a ketone molecule.
