Carboxylic acid can be changed to acid chloride by the treatment with:
Correct answer: B. SOCl2
- A. S2Cl2
- B. SOCl2
- C. HCl
- D. HOCl
Explanation
SOCl2 is correct because it is commonly used in the conversion of carboxylic acids to acid chlorides through an acyl chloride intermediate. This process is known as the "Thionyl chloride method" or "Vilsmeier-Haack reaction." SOCl2 reacts with the carboxylic acid to form an acyl chloride and sulfur dioxide gas

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.
