Question

Examine the structures represented by the following models. Atoms other than carbon and hydrogen are indicated by the element symbol.

A B C
-Which would have an acidic pK_a?

Quizplus · Accepted Answer

The structure represented by model B contains a carboxylic acid functional group, which is a known acidic functional group with a pKa range of approximately 3-5. This indicates that the molecule would have an acidic pKa value. Therefore, choice B is the correct answer. Structures A and C do not contain any functional groups that would give rise to an acidic pKa.
