Identify the product X in the following reaction: CH3COOH + SOCl2 ⟶ X + SO2 + HCI
Correct answer: A. CH3COCI
- A. CH3COCI
- B. CH2ClCOCI2
- C. CH3COCH2CI2
- D. CH2COCl2
Explanation
The carboxylic acid reacts with SOCl2 to form acid chloride. In the reaction, the hydroxyl group of the carboxylic acid is converted to an intermediate which then makes it a better leaving group.The sulfur in thionyl chloride is a strong electrophile and carboxylic acid can act as a nucleophile. So X in this reaction is acid chloride. CH3COOH + SOCl2→ CH3COCl + SO2 + HCl

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.
