Text Solution

Verified by Experts

The correct Answer is:
A
The `-OH` group of alcohol or the `-COOH` group of a carboxylic acid is replaced by `-Cl` using phosphorus pentachloride (i.e., `PCl_(5)`)
`underset("Alcohol")(ROH)+PCl_(5) rarr R Cl +POCl_(3)+HCl`
`underset("Acid")(RCOOH)+PCl_(5)rarr RCOCl +POCl_(3)+HCl`
