CH3COOH + PCI3⟶?The products of the above reaction are:
Correct answer: A. CH3COCI + H3PO3
- A. CH3COCI + H3PO3
- B. CH3CI + POCI3 + HCI
- C. CH3COCI + POCl2 + HCl
- D. CH3COCI + POCI3 + H2
Explanation
By using PCl3 as the chlorinating reagent, various carboxylic acids are converted into the corresponding acid chlorides in good yields. This method features high atom efficiency in which nearly all three chlorine atoms of PCl3 are used in the chlorination.The balanced equation for the reaction between acetic acid and PCl3 is given below: 3CH3COOH + PCl3 → 3CH3COCl + H3PO3

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.
