The stronger acid among the following is:
Correct answer: A. CI3CCOOH
- A. CI3CCOOH
- B. CICH2COOH
- C. Cl2CHCOOH
- D. CH3COOH
Explanation
The acidity of haloacetic acids is increased by the electron-withdrawing inductive effect of the halogen atoms. The more halogen atoms there are. the stronger the effect and the stronger the acid. Trichloroacetic acid (CCI3COOH) is therefore the strongest.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
