Which of the following reactions may be associated with aldehyde and ketone?
Correct answer: D. all
- A. nucleophile addition
- B. polymerization
- C. oxidation
- D. all
Explanation
The correct answer is:(d) AllHere's why:Aldehydes and ketones are incredibly versatile functional groups and participate in a wide range of reactions, including:Nucleophilic addition: This is one of the most common reactions for aldehydes and ketones, involving the attack of a nucleophile (electron-rich species) on the electron-deficient carbonyl carbon. Examples include reactions with Grignard reagents, hydride reagents, and cyanide ions.Oxidation: Certain aldehydes and ketones can be oxidized under specific conditions. For example, aldehydes can be oxidized to carboxylic acids using oxidizing agents like Tollen's reagent or dichromate ions.Polymerization: Some aldehydes and ketones can undergo polymerization reactions to form polymers. Formaldehyde, for example, can polymerize to form polyoxymethylene.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
