What are the product when SOCl2 is reacted with acetic acid?
Correct answer: A. Ethanoyl chloride + SO2 + HCl
- A. Ethanoyl chloride + SO2 + HCl
- B. Ethanoyl chloride + SO3
- C. Ethanoyl chloride + HCl + H2SO3
- D. Ethanoyl chloride + HCl + H2SO4
Explanation
Thianyl chloride (SOCI2) is a common reagent used to convert carboxylic acids into acyl chlorides. The reaction replaces the -OH group of the acid with -Cl. producing the acyl chloride (ethanoyl chloride), along with the gaseous byproducts sulfur dioxide (SO₂) and hydrogen chloride (HCI).

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.
