Mechanism for the reactions and requirement of acid in the reaction should be explained. Concept introduction: Carbonyl compound when treated with LDA (Lithium diisopropylamide) undergoes deprotonation at the α carbon to form enolate. The resulted enolate is resonance stabilized by the carbon and oxygen atom. The resonance stabilized intermediate undergoes reaction with other molecule of carbonyl (same or different) to form the respective products. If LDA is used as a base the less substituted α carbon is deprotonated due to steric hindrance.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
