Carboxylic acids can be prepared by action of _ and carbon dioxide
Correct answer: B. Grignard's reagent
- A. Sodium hydroxide
- B. Grignard's reagent
- C. Alcoholic KOH
- D. Alkaline KMnO_4
Explanation
This reaction is known as the "Grignard reaction with carbon dioxide". A Grignard reagent (RMgX, where R is an alkyl or aryl group, and X is a halogen) reacts with carbon dioxide to form a carboxylate salt, which can then be protonated to give the carboxylic 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.
