Question

Acetic acid reacts with $PC{l}_5$ to form :

• A. $CHC{l}_{2}COOH$
• B. $C{H}_{3}COCl$
• C. $C{H}_{3}COOCl$
• D. $C{H}_{2}ClCOOH$

Answer 1

Answer: (B)

Acetic acid reacts with $PC{l}_5$ to form acetyl chloride.

$\underset{\text{acetic acid}}{C{H}_{3}COOH+PC{l}_5}\to \underset{\text{acetyl chloride}}{C{H}_{3}COCl}+POC{l}_3+HCl$
