(a)
Interpretation:
The expected product for the aldol condensation of propanal 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.
(b)
Interpretation:
The expected product for the aldol condensation of phenylacetaldehyde 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.
(c)
Interpretation:
The expected product for the aldol condensation of pentan-3-one 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.
