(a)
Interpretation:
The mechanism for the given reaction is to be proposed.
Concept introduction:
Aldol condensation is defined as a condensation reaction that involves the nucleophilic addition of an enolate ion to another carbonyl group to form a
(b)
Interpretation:
The mechanism for the given reaction is to be proposed.

(c)
Interpretation:
The mechanism for the given reaction is to be proposed.
Concept introduction:
In the claisen-ester condensation, nucleophilic acyl substitution takes place on an ester. The enolate ion acts as a nucleophile. It attacks the carbonyl carbon to form a tetrahedral intermediate. Acidity of beta-keto ester products is higher than simple ketones, aldehydes and esters.
