By treating CO2 with Grignard's reagent following compound is obtained:
Correct answer: C. Carboxylic acids
- A. Aromatic compounds
- B. Alcohols
- C. Carboxylic acids
- D. Ethers
Explanation
Carboxylic acid is obtained by treating Grignard's reagent with CO2 followed by acid hydrolysis. This reaction is either carried out:By passing CO2 through the ethereal sol of corresponding Grignard reagent.Or by adding Grignard reagent to crushed dry ice suspended in ether.The addition product on treatment with mineral acid produces 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.
