In the presence of strong acids, which of the oxygen atoms on the carboxyl group is preferentially protonated and why?

a. Protonation occurs at the carbonyl oxygen because the resulting conjugate acid i stabilized by resonance.
b. Protonation occurs at the carbonyl oxygen because the resulting conjugate base is stabilized by the inductive effect.
c. Protonation occurs at the hydroxyl oxygen because the resulting conjugate acid is stabilized by resonance.
d. Protonation occurs at the hydroxyl oxygen because the resulting conjugate base is stabilized by the inductive effect.

Answer :

Answer:

Protonation occurs at the carbonyl oxygen because the resulting conjugate acid is stabilized by resonance.

Explanation:

The carboxyl group is an organic and a functional group that consists of a carbon atom that's singly bonded to a hydroxyl group and double-bonded to an oxygen atom.

In the presence of strong acids, protonation occurs at the carbonyl oxygen because the resulting conjugate acid is stabilized by resonance.
