Strongest acid among the following is:
Correct answer: A. HCOOH
- A. HCOOH
- B. CH3COOH
- C. (CH3)2CHCOOH
- D. (CH3)3CCOOH
Explanation
Among the given acids, formic acid is the strongest acid.As the number of methyl groups increases, the electron releasing +I effect of substituents decreases the acidity of carboxylic acids by intensifying the negative charge by inductive effect and destabilizing the carboxylate anion.

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.
