A base catalyzed reaction in carbonyl compounds increases the:
Correct answer: A. Nucleophilic character of the attacking reagent only
- A. Nucleophilic character of the attacking reagent only
- B. Electrophilic character of the carbonyl carbon atom only
- C. Electrophilic character of the attacking reagent only
- D. Nucleophilic character of the carbonyl carbon atom only
Explanation
A base-catalyzed reaction in a carbonyl compound increases the nucleophilic character of the attacking reagent only. Explanation: When a base is added to a carbonyl compound, it can abstract a proton from the carbonyl compound, leading to the formation of an enolate ion. The enolate ion is a nucleophile and can attack electrophilic reagents. The base does not affect the electrophilic character of the carbonyl carbon atom but instead increases the nucleophilic character of the attacking reagent, which can lead to the formation of a new bond.

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.
