Aldehydes and ketones both react with hydroxylamine to form
Correct answer: A. oximes
- A. oximes
- B. esters
- C. alcohols
- D. amines
Explanation
The nitrogen of hydroxylamine attacks the carbonyl carbon and water is then eliminated, so the product contains a carbon to nitrogen double bond and is called an oxime. Hydrazine and its derivatives react in the same condensation pattern to give hydrazones. These crystalline derivatives were once the standard way to identify a carbonyl compound from its melting point.

About Nucleophilic Addition Reactions
Nucleophilic addition occurs at the polar carbonyl group of aldehydes and ketones, where a nucleophile attacks the electron-deficient carbon atom. Reactions with hydrogen cyanide, sodium bisulfite, alcohols and Grignard reagents are explained through tetrahedral intermediates, acid or base catalysis, and the different reactivity of aldehydes and ketones.
