Vedclass · Answer

(D) In the first molecule,the circled hydrogen is part of an alcohol group attached to a carbon with a strong electron-withdrawing $CF_3$ group,making it more acidic than the primary alcohol. In the second molecule,the circled hydrogen is the carboxylic acid proton,which is significantly more acidic than the hydroxyl group. In the third molecule,the circled hydrogen is at the allylic/benzylic position,which is acidic due to the resonance stabilization of the resulting carbanion. Since all representations correctly identify the most acidic hydrogen in their respective molecules,the correct answer is $D$.

Circles represent the most acidic hydrogens in these molecules. Which of the following is the correct representation?
