Organic Chemistry: Some Basic Principles and Techniques

The compound that is most difficult to protonate (at the carbonyl oxygen) among the following is:

  1. A.Formaldehyde, HCHO\mathrm{HCHO}
  2. B.Acetaldehyde, CH3CHO\mathrm{CH_3CHO}
  3. C.Acetone, CH3COCH3\mathrm{CH_3COCH_3}
  4. D.Benzaldehyde, C6H5CHO\mathrm{C_6H_5CHO}✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
