Aldehydes and ketones react with ammonia derivatives C-NH2 toform condensation product containing the group C = N - C and water. The reaction is:
Correct answer: B. Acid catalyzed only
- A. Base catalyzed only
- B. Acid catalyzed only
- C. Both A and B
- D. Neither A nor B
Explanation
Option B is correct. It is an acid catalyzed reaction because as the H+ eliminates from the acid it combines with carbonyl oxygen to increase the electrophilic character of carbonyl carbon hence making the attack of nucleophile easier.

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.
