Question:
Which from following is the strongest haloacetic acid?
Which from following is the strongest haloacetic acid?
Show Hint
The more electronegative the halogen, the stronger its electron withdrawing (-I) effect and the stronger the acid.
Updated On: Nov 13, 2026
Fluoroacetic acid
Bromoacetic acid
Chloroacetic acid
Iodoacetic acid
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
In haloacetic acids the halogen atom pulls electron density away from the carboxylate group through the -I effect, which stabilises the anion and increases acidity.
Step 2: Trend in electronegativity
Electronegativity order is \(\text{F} > \text{Cl} > \text{Br} > \text{I}\).
Step 3: Acid strength order
Hence acid strength is \(\text{FCH}_2\text{COOH} > \text{ClCH}_2\text{COOH} > \text{BrCH}_2\text{COOH} > \text{ICH}_2\text{COOH}\).
Step 4: Compare the options
Fluoroacetic acid is the strongest.
Final Answer:
Fluoroacetic acid is the strongest haloacetic acid. \[ \boxed{\text{(A) }\text{Fluoroacetic acid}} \]
