The following figure shows the electrostatic potential maps of the molecules CH₃COOH and CF₃COOH. Determine the most acidic hydrogen in each molecule. Compare their acidity and identify which is expected to be a stronger acid between the two.

• A. For CH₃COOH, the H in –CH₃ is the most acidic hydrogen while for CF₃COOH, the H in –COOH is the most acidic hydrogen.
  CH₃COOH is more acidic.
• B. For CH₃COOH, the H in –CH₃ is the most acidic hydrogen while for CF₃COOH, the H in –COOH is the most acidic hydrogen.
  CF₃COOH is more acidic.
• C. For both molecules, the H in –COOH is the most acidic hydrogen.
  CH₃COOH is more acidic.
• D. For both molecules, the H in –COOH is the most acidic hydrogen.
  CF₃COOH is more acidic.

Answer: (D)
