Answer 2

The reaction forms Dichlorobenzene

Explanation:

• Reaction of ketone with phosphorus pentachloride results in the formation of geminal dichloride .
• This happens due to displacement of the oxygen atom when chlorination occurs at the carbonyl carbon.
• In this case , a quinone called p-benzoquinone or 1,4-benzoquinone is made to react with $PCl_5$ , which forms 1,4- dichlorobenzene , with chlorine atom substituted at 2 para positions in place of keto bonds.
• In addition , $POCl_3$ is formed is formed as a product.
• An image has been attached to demonstrate the reaction.
