NMR
Proton NMR spectrum for a compound of molecular formula C6H12O2.
The ketone has four different types of protons. There are two equivalent methyl groups labeled a that will have the same signal, a methyl (b) and a methylene (c) directly attached to the carbonyl so they will be deshielded, and a hydroxyl proton (d). Since there is only one hydroxyl proton the height of the integration line for this signal will represent 1 proton. The methylene (c) integration line will be twice as high as (d), the methyl (b) three times higher, and the integration for the six protons of the methyls (a) will be six times higher than (d).
