Preparation of an a,b-unsaturated ketone via Michael and Aldol
reactions
The carbon next to the carbonyl (C=O) carbon is called the a
carbon and the carbon next to the a carbon is called the b carbon.
An a,b-unsaturated car- bonyl compound is a carbonyl compound
(aldehyde, ketone, ester, etc.) that has a multiple (double or
triple) bond between the a carbon and the b carbon.
As part of your post-lab report, analyze your spectra.
