Correct statement by changing underline part of sentence
Formic acid `ul("undergoes")` halogenation.

Explanation

To correct the statement "Formic acid undergoes halogenation," we need to change the underlined part of the sentence.

**Step 1: Identify the correct term to replace "undergoes."**
Formic acid does not undergo halogenation because it lacks alpha hydrogen atoms. Halogenation requires the presence of alpha hydrogen, which formic acid does not have.

**Step 2: Rewrite the sentence with the correct term.**
The corrected statement should be: "Formic acid **does not undergo** halogenation."
