Solution

The correct options are
A $S O C l_{2}$
B $P C l_{5}$
C $P C l_{3}$
A carboxylic acid, $R C O O H$ can be converted into an acyl chloride $R C O C l$ by replacing $- O H$ with $- C l$ using $P C l_{5}$ , $P C l_{3}$ or $S O C l_{2}$ . The chloride anion produced during the reaction acts a nucleophile and attacks on the carbonyl $C$ and forms $R C O C l$ .

$R C O O H + P C l_{5} \to R C O C l + P O C l_{3} + H C l$
$R C O O H + P C l_{3} \to R C O C l + H_{3} P O_{3}$
$R C O O H + S O C l_{2} \to R C O C l + S O_{2} + H C l$

Option A, B And C are correct.
