Question

Which is more basic oxygen in an ester?

• A. Carbonyl oxygen, \( \alpha \)
• B. Carboxyl oxygen, \( \beta \)
• C. Equally basic
• D. Both are acidic oxygen

Hint:

The carbonyl oxygen in esters is more basic than the carboxyl oxygen, as it is less electron-withdrawing.

Answer 1

The Correct Option is A

Step 1: Understanding ester basicity.
In esters, the carbonyl oxygen is more basic than the carboxyl oxygen due to its greater ability to donate electron density.

Step 2: Conclusion.
The carbonyl oxygen is more basic, corresponding to option (1).
