acetophenone reacts with pcl5 to form.....? plz give the correct answers!!

pcl5
When a ketone is treated with phophorus pentachloride, chlorination occurs at the carbonyl carbon by displacement of the oxygen atom. A geminal dichloride results in such a reaction. For instance, acetone is converted to 2,2-dichloropropane by the action of PCl5.
Acetophenone can react with phosphorus pentachloride (PCl5) to form α-chloroacetophenone and hydrogen chloride gas (HCl) as products.
The reaction can be represented as follows:
C6H5C(O)CH3 + PCl5 → C6H5C(Cl)(O)CH3 + POCl3 + HCl
In this reaction, one of the chlorine atoms in PCl5 replaces the carbonyl group oxygen in acetophenone, resulting in the formation of α-chloroacetophenone. The other products, POCl3 and HCl, are formed due to the reaction of PCl5 with the released H2O molecule from the reaction.
Alpha-chloroacetophenone is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals.
