a)
Interpretation:
The enone product expected from the aldol condensation of cyclopentanone is to be given.
Concept introduction:
To give:
The enone product expected from the aldol condensation of cyclopentanone.
b)
Interpretation:
The enone product expected from the aldol condensation of acetophenone is to be given.
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, a β-hydroxyaldehyde or ketone upon heating eliminate a molecule of water to yield the enones, α,β-unsaturated aldehydes or ketones.
To give:
The enone product expected from the aldol condensation of acetophenone.
c)
Interpretation:
The enone product expected from the aldol condensation of 2-methylbutanal is to be given.
