Provide evidence of how you
also used NMR and mass spec to identify your Unknown?Butanone
The NMR (C NMR or H NMR) determines a few characteristics.
The C NMR identified the different carbons in the molecule and what types they
were. Eg sp3, C=C, C=O etc. The H NMR displays the integration and
the number of H’s and information of the H neighbours. The shifts can help you
identify the electronic environment of H
The Mass Spectrum helps identify the
molecular formula and if a halogen is present and which one.
This is how I did used the above how to
identify.

NMR(proton NMR) 
The chemical shift positions for Proton NMR spectra is predicted for butanone as – 
CH3C
H2
H3C
O
2.09
2.49
1.06
 
The alpha hydrogens get greater chemical shift due to higher desheilding effect of carbonyl group. 
Hence 2 alpha hydrogens have nearly same value ( 2.09 ).
