Carboxylic acids do not give the characteristics reaction of >C=O group because of:
Correct answer: C. Resonance
- A. Polar nature
- B. Attached alkyl group
- C. Resonance
- D. Symmetrical structure
Explanation
The carbonyl group of ketones & aldehydes is more. electrophilic than in carboxylic acids. This is because the lone pairs on the Oxygen atom attached to a Hydrogen atom in the CO2H are involved in 'resonance', thereby making the carbon atom less electrophilic.

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.
