(a)
Interpretation:
The mechanism for the given reaction is to be stated.
Concept introduction:
In acid-catalysed Aldol condensation, nucleophilic addition of an enol takes place at a protonated carbonyl group. In the first step, enol is formed when carbonyl oxygen gets protonated. Then, deprotonation occurs at alpha carbon. In the next step, enol adds to the protonated carbonyl followed by deprotonation to give the aldol product.

The mechanism for the given reaction is to be stated.

(c)
Interpretation:
The mechanism for the given reaction is to be stated.
Concept introduction:
In base-catalysed aldol condensation, nucleophilic addition of an enolate ion takes place on a carbonyl group. In first step, an alpha proton is removed to produce enolate ion. It adds to the carbonyl group. In the next step, protonation of alkoxide gives the aldol product.
