Question

1. What is meant by an enolizable carbonyl compound? What group of bonds must be present in the molecules for a compound to fit this description?

2. Show the structures of the various possible products formed when two enolizable carbonyl compounds (say, acetone and acetophenone) are subjected to conditions necessary for the mixed aldol condensation?

3. To be synthetically useful, mixed-aldol condensation should make use of only 1 enolizable carbonyl compound. Explain.
