What is the strongest acid among the following?

Question

Quizplus · Accepted Answer

The strength of an acid in organic molecules like these is influenced by the ability of the molecule to stabilize the negative charge on the conjugate base after deprotonation. The presence of electronegative elements (like chlorine) that can delocalize this charge through resonance or inductive effects generally increases acid strength. Option D, trichloroacetic acid, has three chlorine atoms that greatly stabilize the negative charge on the conjugate base through their strong inductive effects, making it the strongest acid among the given options.
