Solution
Correct Answer:
Aldehyde/ketone with α-hydrogen and base
The Aldol Condensation is a crucial C-C bond-forming reaction.
- Requirement: An aldehyde or ketone must possess at least one α-hydrogen atom.
- Mechanism: A base (like dilute NaOH) abstracts the acidic α-hydrogen to form a resonance-stabilized enolate ion. This ion then acts as a nucleophile, attacking the carbonyl carbon of another molecule.
- Product: A β-hydroxy aldehyde (Aldol) or β-hydroxy ketone, which often dehydrates on heating to form an α,β-unsaturated carbonyl compound.
This easy difficulty chemistry question is from the chapter organic compounds containing oxygen, covering the topic of aldol condensation. It appeared in the 2025 exam.
