Acetic acid exists as dimer in benzene due to:
Correct answer: D. Hydrogen bonding
- A. Presence of hydrogen at ∞-carbon
- B. Condensation reaction
- C. Presence of carboxylic group
- D. Hydrogen bonding
Explanation
The oxygen atom carbonyl group of one carboxylic acid forms hydrogen bond with hydrogen atom of hydroxyl group of other carboxylic acid. Similarly, hydrogen atom of hydroxyl group of one carboxylic acid forms hydrogen bond with the oxygen atom carbonyl group of other carboxylic acid which results in formation of dimer.

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.
