Which of the following is not an example of an acid-base reaction?
Correct answer: D. Reaction of CH₃COOH with PCl₅
- A. Reaction of CH₃COOH with Na
- B. Reaction of CH₃COOH with NaHCO₃
- C. Reaction of CH₃COOH with Na₂CO₃
- D. Reaction of CH₃COOH with PCl₅
Explanation
The reaction of a carboxylic acid with PCI5 is a nucleophilic acyl substitution, not an acid-base reaction. The other options all involve the carboxylic acid acting as a proton donor (an acid)

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.
