Correct answer: A. FCH2COOH
- A. FCH2COOH
- B. CICH2COOH
- C. BrCH2COOH
- D. ICH2COOH
Explanation
Fluorine is the most electronegative halogen. The electron-withdrawing effect of fluorine increases the acidity of the carboxylic acid by stabilizing the conjugate base. Thus, fluoroacetic acid is the strongest acid among the options provided.
