Aldehyde and ketone on reaction with hydroxylamine form:
Correct answer: C. Oxime
- A. Hydrazine
- B. Hydrazone
- C. Oxime
- D. Imine
Explanation
When aldehydes and ketones react with hydroxylamine (NH₂OH), they form a class of compounds known as oximes. The reaction involves the nucleophilic addition of hydroxylamine to the carbonyl group (C=O) of the aldehyde or ketone, resulting in the formation of an oxime, which contains the functional group C=N-OH.

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.
