Concept introduction:
To state:
Whether 2-hydroxy-2-methylpentanal is an aldol condensation product or not. Further to state the aldehyde or ketone precursor from which it can be prepared.
b) 5-Ethyl-4-methyl-4-hepten-3-one
Interpretation:
Whether 5-ethyl-4-methyl4-heptene-3-one is an aldol condensation product or not is to be stated. The aldehyde or ketone precursor from which it can be prepared also is to be stated.
Concept introduction:
Aldehydes and ketones with α-hydrogen undergo a base catalyzed carbonyl condensation reaction in aldol condensation. In this reaction two molecules of the reactant combine by forming a bond between α-carbon of one molecule and the carbonyl carbon of the second molecule. The product obtained is a β-hydroxyaldehyde or ketone.
To state:
Whether 5-Ethyl-4-methyl-4-heptene-3-one is an aldol condensation product or not. Further to state the aldehyde or ketone precursor from which it can be prepared.
