What stabilizes the conjugate base of a carboxylic acid, the carboxylate ion?

Options

  1. ATwo equivalent resonance structures with the negative charge on the more electronegative oxygen atom
  2. BTwo equivalent resonance structures with the negative charge on the carbon atom
  3. CNon-equivalent resonance structures with the negative charge on the less electronegative carbon atom
  4. DNon-equivalent resonance structures with the negative charge on the oxygen atom

Correct answer

A. Two equivalent resonance structures with the negative charge on the more electronegative oxygen atom

Step-by-step solution

The conjugate base of a carboxylic acid, the carboxylate ion, is stabilized by two equivalent resonance structures in which the negative charge is on the more electronegative oxygen atom.
