With reference to the carbonyl group, which statement(s) is/are correct?
Show Hint
Carbonyl carbon is electrophilic due to δ+; carbonyl oxygen is nucleophilic due to lone pairs.
Updated On: Jun 26, 2026
- Carbonyl Carbon is electrophilic
- Carbonyl Carbon is nucleophilic
- Carbonyl Oxygen is electrophilic
- Carbonyl Oxygen is nucleophilic
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Structure of carbonyl group.
C=O bond has partial positive charge on carbon and partial negative charge on oxygen due to electronegativity difference.
Step 2: Electrophilic carbon.
The carbonyl carbon is electron deficient → electrophilic.
Step 3: Nucleophilic oxygen.
The carbonyl oxygen has lone pairs → nucleophilic and can act as a base.
Step 4: Incorrect options.
- Carbonyl carbon is not nucleophilic.
- Carbonyl oxygen is not electrophilic.
Step 5: Conclusion.
\[ \boxed{\text{Correct statements: a and d}} \]
