When acetone reacts with phosphorous pentoxide it will result into the formation of 2,2-dichloropropane and a byproduct phosphoryl chloride (phosphorous oxychloride).

The main compound formed is a geminal dihalide (dichloride), in which the both halogen atoms are attached to same carbon atom.

This product is formed by replacing oxygen atom of carbonyl group by chlorine atoms.

I.V.Srinivasa Reddy

It will resulting in production of 2,2 dichloro propane and phosphorous oxychloride
