Question
Chapter 2, Problem 76P
Interpretation Introduction
Interpretation: To determine the most acidic hydrogen in caffeic acid.
Concept Introduction: Acidic hydrogen can be identified by its attachment to an extremely electronegative atom of oxygen, the hydrogen atom in the acidic group would be the most acidic. It is acidic because the hydrogen atom is joined to an oxygen atom, which is then joined to a carbon atom through a double bond.
