Answer
The "Base Y" has the stronger conjugate acid. This is because, as we determined in (38b), "Base Y" is the weaker base, and the strength of the base is inversely proportional to the strength of the conjugate acid.
Work Step by Step
- The strength of a base is inversely proportional to the strength of its conjugate acid.
Therefore, stronger bases have weaker conjugate acids, and weaker bases have stronger conjugate acids.
Since "Base Y" is the weaker base of the pair, it will have the stronger conjugate acid.
