Question:
Identify the product obtained when acetic acid reacts with \(\text{PCl}_{5}\).
Identify the product obtained when acetic acid reacts with \(\text{PCl}_{5}\).
Show Hint
PCl5 replaces the -OH of a carboxylic acid by Cl.

- \(\text{CH}_{2}\text{ClCOOH}\)
- \(\text{CH}_{3}\text{COOCl}\)
- \(\text{CH}_{3}\text{COCl}\)
- \(\text{CHCl}_{2}\text{COOH}\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Carboxylic acids react with \(\text{PCl}_{5}\) to form acid chlorides.
Step 2: Reaction
\(\text{CH}_{3}\text{COOH}+\text{PCl}_{5}\rightarrow \text{CH}_{3}\text{COCl}+\text{POCl}_{3}+\text{HCl}\)
Step 3: Product
The \(-\text{OH}\) group is replaced by \(-\text{Cl}\), giving acetyl chloride, \(\text{CH}_{3}\text{COCl}\).
Final Answer:
The product is acetyl chloride. \[ \boxed{\text{(C) }\text{CH}_{3}\text{COCl}} \]
