Question
From the h nmr and c nmr of the unknown carbonyl compound determine its structure and draw it, label each c, ch, ch2, or ch3 group using letters (a,b,c) and assign each peak in the proton and carbon nmr spectrum to the carbons and hydrogens that correspond to it in the molecule.
Example of what should be included in the table:
hydrogen/carbon | carbon chemical shift | hydrogen chemical shift | splitting pattern | integral | couples to |
