OCHEM Experiment: This video is about Aldehyde & Ketone Reactions.
Part A: Oxidation- Tollens’ Silver Mirror Test
Aldehydes and ketones react differently towards oxidizing agents. Aldehydes are easily oxidized to acids with the same number of carbon atoms.
Part B: Addition Reactions
Bisulfite Addition compounds. Aldehydes and some ketones react with saturated aqueous sodium bisulfite to form white crystalline addition products. The nucleophile is the bisulfite ion.
Part C: Reactions of Enolate Anions
Enolate anions can act as nucleophiles in many reactions. Enolate anions react rapidly with halogens to give α-halocarbonyl compounds.
Part D: The Aldol Condensation:
Enolate anions can add to carbonyl groups since they are nucleophiles. When acetaldehyde is treated with dilute base, it condenses with itself to give aldol. Upon heating, the aldol loses water, giving the unsaturated aldehyde, crotonaldehyde.
