For aldol condensation, carbonyl system must have _.
Correct answer: D. Alpha hydrogen
- A. Beta hydrogen
- B. Beta carbon
- C. Alpha carbon
- D. Alpha hydrogen
Explanation
Alpha hydrogens are hydrogen atoms directly attached to the carbon atoms adjacent to the carbonyl carbon. The presence of these alpha hydrogens is essential for the mechanism of aldol condensation, as they participate in the formation of the enolate intermediate, which is a key step in the reaction.

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.
